You went to bed in your body and woke up in a stranger’s. The first stair sends a bolt through one knee. Your hips throb at 3 a.m. for no reason you can name. Your fingers, the ones that have typed and cooked and held children for decades, are stiff and swollen by morning and slow to forgive you. Nothing happened. You did not fall. You did not train for a marathon. The pain simply arrived, and it is not subtle, and it does not retreat.

So you do the responsible thing. You go to the doctor. They order the imaging, run the labs, press on the joint, and then they tell you, in a voice meant to reassure, that everything looks fine. No arthritis they can see. No tear. No explanation. And somewhere in that appointment, spoken or not, lands the sentence that does the real damage: maybe this is just what getting older feels like.

It is not. What is happening to you has a mechanism, a name, and a growing body of research behind it. But to see it clearly, you have to understand one process most people, including most doctors, explain badly or not at all. So we are going to build it slowly, from the ground up, until it is yours. By the end you will not only understand your own pain. You will be able to explain it to any woman who needs to hear it.

Start here because everything rests on it

Most people picture inflammation as swelling. A rolled ankle, hot and red and puffy. That is acute inflammation, and it is one of the most elegant systems your body owns. You cut your finger, and within minutes the immune system floods the area with cells and fluid, walls off the damage, kills any invaders, clears the debris, and then, crucially, shuts the whole operation down. Beginning, middle, end. The swelling you can see is the system working, and then finishing.

To do that work, immune cells have to talk to each other, and they talk using chemical messengers called cytokines. Think of cytokines as text messages between immune cells. Some cytokines say send help, this is serious. Others say stand down, the threat is handled. A few names will come up again and again, in this article and inside your own body: IL-6, TNF-alpha, and IL-1-beta. All you need to hold onto is that these are the immune system’s alarm messages, the texts that mean something is wrong here, respond. In acute inflammation, these messages surge and then fall silent. The alarm rings, the job gets done, the phone goes quiet.

Chronic systemic inflammation is what happens when the phone never stops buzzing. The alarm messages keep going out at a low volume, day and night, for years, with no injury to justify them and no off-switch strong enough to stop them. There is no cut finger. There is no infection. And yet the messages keep circulating, quietly, constantly, holding the entire body in a low state of defense that never lifts. If acute inflammation is getting punched, chronic inflammation is an ill-fitting shoe you never take off. No wound, nothing you would call an injury, just a low constant rub, every step, every day, for years. And that quiet, endless friction does more cumulative damage than the punch ever could.

So the only question that actually matters is this: why do the messages never stop? The answer is the most useful thing you will read about your own body this year.

An alarm switched on through doors, switched off through brakes

Your body runs that inflammatory alarm on a simple logic. It gets switched on through several doors, and switched off through several brakes. In a body that is working well, the doors mostly stay shut and the brakes mostly work, so the alarm sounds only when it is truly needed and stops the moment the job is done. Chronic inflammation sets in when too many doors are propped open at the same time that the brakes begin to fail. More things ringing the alarm, fewer things able to silence it. Let me walk you through both sides because once you see them, you cannot unsee them.

The doors that ring the alarm

One thing matters more than any single door, so hold it as you read all four. Every one of these describes a normal, healthy immune response. Your body is supposed to react exactly as it does at each door. So the question is never why does my body react at all. The reaction is correct. The real question, the one that separates a healthy body from an inflamed one, is why the reaction never switches off.

Overstuffed fat cells. Fat is not inert padding. It is a living, hormonally active organ. In chronic energy overload, your fat cells swell past the size their own blood supply can serve, and some of them suffocate and die. Immune cells called macrophages move in to clear away the dead cells, and so far this is exactly right. This is their job, and you want them there. But because the overfeeding does not stop, the dying does not stop, so the macrophages never get to leave. They pile up, cluster around the dead cells, and, overwhelmed and stuck in the tissue, they change character. They stop being a quiet cleanup crew and switch into an attack posture, pouring alarm cytokines, TNF-alpha and IL-6, into the bloodstream. Worse, those cytokines make the neighboring fat cells sicker and more likely to die, which draws in still more macrophages, which release still more cytokines. A helpful cleanup has curdled into a self-feeding fire that no longer switches off. That is the whole difference. Not the cleanup. The fact that it never ends.

A high-sugar, heavily processed diet. You do not even need a dying cell to ring the alarm, and this is the mechanism almost everyone skips. Your immune cells are studded with danger sensors, and the most important is called TLR4. Its real job is to detect a scrap of bacterial cell wall, the unmistakable calling card of an invader, and to fire the moment it finds one. Here is the twist. That very same sensor is tripped by the molecular signature of dietary overload. The saturated fat and the oxidized fat particles that flood your blood after a heavily processed meal switch on that same TLR4 danger pathway, so the immune cell reacts to a greasy, sugary bloodstream as though it had met a bacterium. On top of that, chronically high blood sugar forces your cells to burn it in a way that throws off sparks, a process called oxidative stress, and those sparks flip the same inflammatory switch. Eat one such meal and the alarm rings briefly and settles. Eat this way day after day, year after year, and it never fully settles. The low hum becomes your baseline.

A leaky gut lining. This is the door almost no one talks about, and once you see it you cannot unsee it. Your gut wall is a single layer of cells, stitched together by proteins called tight junctions, and its job is to let nutrients through while keeping the trillions of bacteria that live in your gut on their own side. When those junctions loosen, fragments of that bacteria seep through into the bloodstream, where they absolutely do not belong. Your immune system finds them and responds exactly as it should, as though to an infection. That response is correct. The problem, again, is that it has no finish line. A real infection ends: you kill the invader, resolve, and stand down. But a leaky gut is not an invasion you can win. It is a slow, continuous seep, hour after hour, day after day, so the immune system is held permanently, faintly switched on, answering a trickle that never stops. And these bacterial fragments happen to be among the most powerful alarm triggers your body owns, which is why so quiet a leak punches so far above its size. It has a name, metabolic endotoxemia, and it runs in the background of an enormous number of inflamed bodies. Hold onto this door. Estrogen turns out to be one of the main things that keeps it shut.

Aging cells that will not die. As the years pass, more and more cells reach the end of their useful life but refuse to die off the way they should. These are called senescent cells, and they sit in your tissues like smoldering embers, leaking alarm cytokines without pause. Normally your immune system would clear them out, but that housekeeping slows with age, so they accumulate, and each one becomes a small, permanent source of a signal that is never allowed to switch off.

Now step back and see the single pattern beneath every one of these doors. This is the sentence that makes chronic inflammation finally make sense. Acute inflammation is healthy precisely because it ends. It is a fire that flares to do a job and then burns out. Every door above lights that same healthy fire for a real reason. What turns it into chronic inflammation is not that the fire is wrong. It is that the match is never taken away. Overfeeding, processed food, a leaking gut, accumulating dead cells, each one keeps striking the match, hour after hour, so the fire is never permitted to go out. And a fire that never goes out stops being a small, local, temporary thing. Its smoke, which is to say the cytokines, drifts out of the fat or the gut where it started, spills into the bloodstream, and travels to every corner of the body. That is the missing link to your joints, and we will follow the smoke there in a moment.

The brakes that should switch it off

This is the half that gets ignored, and for a midlife woman it is the more important half. This is where her body changes the most.

Cortisol, and why chronic stress breaks it. Here is something most people have backwards. Cortisol, the stress hormone everyone treats as the villain, is actually the body’s single most powerful anti-inflammatory brake. In a normal stress response, cortisol rises and then travels to your immune cells, docks onto receptors on their surface, and delivers one clear instruction: stand down, stop making cytokines, the emergency is over. That is cortisol doing one of its most important jobs. The trouble begins when stress never lets up. When cortisol stays high month after month, the immune cells grow tired of hearing it and start pulling those receptors off their surface, ignoring the signal. Scientists call this glucocorticoid resistance. The cortisol is still there, still shouting stand down, but the immune cells have gone deaf to it. And so the inflammation cortisol should be switching off is left to run. Read that twice because it inverts everything you have been told. Chronic stress does not inflame you by adding fuel. It inflames you by disabling the brake.

Muscle. Every time a muscle contracts, it releases its own set of anti-inflammatory signals into the bloodstream. Working muscle is, quite literally, a source of all clear messages. A body that rarely moves loses that built-in brake, which is one reason a sedentary life is an inflamed life.

Sleep. Deep sleep is the body’s nightly maintenance shift, the hours when much of the day’s inflammatory activity is cleared out and the system is reset for morning. Lose that sleep and the alarm never gets its nightly stand-down. And there is a direct, physical reason short sleep also props open the gut door, rather than a vague claim that it simply does. Your gut lining runs on a daily clock, and it does much of its repair and resealing, patching those tight junctions, while you sleep. Cut the sleep short and you interrupt that overnight resealing. Short sleep is also a physical stressor in its own right, so it drives cortisol up, and, as you are about to see, elevated cortisol itself loosens the very same tight junctions. So a poorly slept body becomes a leakier body, on both counts, which quietly props the gut door open from the brake side. Sleep loss hits both halves of the equation at once.

Estrogen. And here is the one that changes everything in midlife. Estrogen was quietly working several brakes at the same time. It helped hold the gut lining tight, keeping that leaky-gut door shut. It is directly anti-inflammatory in its own right, actively quieting the production of the alarm cytokines. And it helped keep the whole stress-and-cortisol system regulated. Estrogen was never one brake. It was a hand resting on several at once.

Now put the two halves together because this is the entire thing. Chronic inflammation is not one broken part. It is a body in which several doors have swung open, overstuffed fat, or processed food, or a leaky gut, or accumulating dead cells, at the very same time that the brakes are failing, deaf cortisol receptors, unused muscle, lost sleep, and falling estrogen. More alarms ringing, fewer able to silence them, all at a low hum, all the time.

The whole picture on one page: more doors propped open while more brakes slip, all at a low level, all the time.

And this is why it was never a story about being overweight. A lean woman who is chronically stressed, sleeping badly, and losing estrogen in perimenopause is inflamed too because her doors are open and her brakes are slipping regardless of her size. Body size is one possible door among many. It is not the mechanism. The mechanism is doors and brakes.

Why a low hum does so much damage

A single burst of cytokines is protective and brief. The damage of chronic inflammation comes from the never-ending version, a body held in a low, standing state of defense for years, and that constant signal wears down one system after another. It interferes with insulin, worsening insulin resistance from the inside. It inflames the lining of your blood vessels, an early step in how arterial plaque builds. It reaches the brain, where it shows up as fog, low mood, and the heavy three o’clock fatigue you already recognize. It muddies the signal of leptin, the hormone that tells you that you are full, so appetite gets harder to read. And it is one of the central drivers of how the body ages, a process now so well established that scientists gave it a name, inflammaging. The cytokines are not the problem in themselves. The problem is that their low signal never stops, and a body kept in a quiet state of emergency for years pays for it everywhere. That is the smoke we promised to follow, and here is where it lands for you. Carried by the blood, those same cytokines reach your joints, where they seep into the cartilage and the joint lining and go to work, driving the enzymes that break cartilage down, inflaming the tissue, and turning up the pain nerves. The ache in your knee is not separate from the fire in your gut or your fat. It is the smoke from that fire, arriving.

“

Chronic stress does not inflame you by adding fuel. It inflames you by disabling the brake.

Why the damage builds and the healing lags

There is a fair question sitting underneath all of this. If inflammation is the immune system running too hot, does that mean the immune system is strong, or weak? The honest answer is neither. It is dysregulated, and dysregulated in a way that hurts joints twice over.

Understand what a healthy immune system actually does. It does not only start inflammation. It also ends it, deliberately, through an active process of resolution, sending in specialized signals and cleanup cells that clear the debris and shut the response down. And it does a third thing that matters enormously for joints. It runs repair. The very same immune cells that fight also direct the rebuilding of tissue afterward, shifting out of attack mode and into repair mode once the threat is handled.

As we age, and especially as estrogen falls, two things happen to this system at once, and both have clumsy names worth knowing. The first is inflammaging, the drift toward the chronic low hum we just described. The second is immunosenescence, a gradual decline in the parts of the immune system that mount clean, effective, well-resolved responses and clear away those senescent cells. In plain terms, the alarm side of the system gets louder while the repair-and-resolution side gets weaker. The body becomes more inflamed and less able to finish the job of healing, at the same time.

Chronic stress pushes this in exactly the wrong direction. Decades of research show that sustained psychological stress both raises inflammatory cytokines and measurably slows the healing of actual wounds. The same forces that ring the alarm also blunt the repair crew.

Now bring it back to the joint. A midlife woman with a dysregulated immune system is not simply someone whose joints hurt. She is someone whose joint tissue is under a constant low inflammatory assault while her body’s capacity to resolve that inflammation and repair the tissue is diminished. The attack is stronger and the repair is slower, at the same time. That is why this does not simply mend on its own the way a sprained ankle did at 25. It is not that her body has forgotten how to heal. It is that the conditions for healing, a calm enough internal environment and a functioning repair system, have been quietly dismantled. Restore those conditions, and the capacity to heal is still there, waiting. That single fact is the reason for hope in this entire article.

“

The attack grows stronger and the repair grows slower, at the same time. That is why it does not simply heal.

The biggest brake of all

Now the estrogen piece falls into place. We have already met most of it. Of every brake on that inflammatory alarm, estrogen was one of the most powerful, and it was resting on several at once.

It helped hold the gut lining tight. Estrogen supports the tight-junction proteins that stitch your gut wall together, so as long as estrogen ran high, that leaky-gut door stayed mostly shut. It was directly anti-inflammatory, actively quieting the production of the alarm cytokines and nudging the immune system toward its calmer, anti-inflammatory setting. And it helped keep the cortisol system regulated, buffering the stress response so it did not run wild.

Then there is the joint itself. Estrogen does not merely circulate past your joints. It acts inside them. Your cartilage, the smooth cap on the end of each bone, your synovium, the lining that produces the fluid lubricating the joint, and your bone are all studded with estrogen receptors, the docking sites called ER-alpha and ER-beta. For most of your adult life, estrogen docked there and did quiet, constant maintenance. It restrained the enzymes, called MMPs, that break down cartilage. It kept the synovial fluid slick. It supported the muscle around the joint. Estrogen is essential for building the fast-twitch muscle fibers and for the muscle stem cells that keep muscle strong. It kept tendons and ligaments elastic. The orthopedic surgeon Vonda Wright, whose work we will come back to, puts it plainly: estrogen is not only a reproductive hormone, it is a musculoskeletal one.

Then perimenopause arrives. And here is the part to understand clearly because it is where most explanations go vague. Estrogen does not simply switch off like a light. Across perimenopause, which unfolds over several years, estrogen swings and spikes and crashes in an increasingly erratic pattern, and the crashes get deeper and more frequent, until, in postmenopause, the hormone settles at a low baseline. So the maintenance estrogen was doing becomes unreliable, then intermittent, then largely gone. The gut door drifts open. The direct anti-inflammatory quieting fades. The cortisol system loses its buffer. And inside the joint, the enzymes that chew cartilage are no longer restrained, the fluid runs less slick, and the tissue is left exposed. Several brakes, all releasing over the same few years, in the same body, at the same time.

“

Estrogen was not one brake. It was a hand resting on several at once. Perimenopause is when the grip begins to fail.

Medicine ran the experiment by accident

If you want to know whether estrogen loss truly causes joint pain, you do not have to guess. Oncology already ran the experiment, without meaning to.

Women with certain breast cancers take a class of drugs called aromatase inhibitors, which work by driving estrogen down to almost nothing. And in study after study, somewhere between 35 and 50 percent of these women develop new or dramatically worse joint pain, often inside the first 6 months, peaking right around the half-year mark.

Same body. New drug. Estrogen stripped out. Joints on fire. This is not a coincidence anyone can wave away. It is a clean causal line running from estrogen to joint pain, drawn by cancer researchers and confirmed thousands of times over. When estrogen falls, joints feel it. The drug simply proves in months what perimenopause does over years.

Where women get hurt twice

The pain of this transition often has no structural cause that a scan can photograph, and that is where women get hurt a second time. The cartilage may not be visibly worn. The joint may not be visibly damaged. In the research, roughly 40 percent of women with these symptoms show no structural findings at all. The problem is not a broken part you can see on a film. The problem is a chemical environment, an inflamed, under-lubricated, pain-sensitized joint, and inflammation does not show up on an X-ray.

So the images come back clean, and the woman gets told the most damaging thing a person in real pain can hear: that nothing is wrong. She gets handed an anti-inflammatory and a shrug. She gets told she is simply getting old. She gets told, in that particular tone, that it might be stress, or her weight, or her imagination. She walks out believing her body has become unreliable, or worse, that she has.

There are two reasons the pain is so real, and together they make the clean scan even crueler. The first is chemical. IL-6, one of those alarm cytokines, does not only degrade tissue. It speaks directly to your pain nerves, turning up the volume on signals a calmer joint would barely register. The second is that pain itself changes over time. When a nervous system processes pain day after day, its pain-carrying pathways can become more responsive and begin amplifying the signal, so you feel more pain, more easily, than the state of the tissue alone would explain. This is called central sensitization, and it is not imagination. It is a measurable change in how the nervous system handles pain. So the ache is real, the sensitivity is real, the amplification is real, and the scan is also clean. All of it is true at once.

In 2024, a team led by the orthopedic surgeon Vonda Wright finally gave this its name in the journal Climacteric: the musculoskeletal syndrome of menopause. It is the whole cluster, joint pain, muscle loss, declining bone density, frozen shoulder, and the accelerated wear of cartilage, all driven by the loss of estrogen. Wright has a precise word for the total-body joint pain that shows up with clean imaging, the kind so many women are told is nothing. She calls it arthralgia, and it was one of her own defining symptoms of perimenopause. More than 70 percent of women will experience some form of this syndrome through the transition. One in 4 will be disabled by it. And most have never once heard the name because the people they trusted with their pain had never learned it either.

“

The scan is clean. The pain is real. Both are true, and the space between them is where women stop being believed.

Close the doors, restore the brakes

So what do you actually do. The good news is that the doors-and-brakes picture that explains the problem also hands you the plan, and it is not a mystery. Everything that helps does one of two things. It closes a door, or it restores a brake. That is the whole strategy, and every step below is one or the other.

First, though, a word about the war most women have been waging because it explains why trying harder has failed them. When a woman’s joints hurt and her weight will not move, the standard prescription is more: harder exercise, deeper restriction, relentless discipline. But her cortisol system is already dysregulated by the loss of estrogen, before she does anything at all. This is not her fault and not something she is doing to herself. As estrogen falls, it stops buffering her stress axis, and her once-reliable daily cortisol rhythm flattens and shifts, often leaving her with too little cortisol in the morning and too much at night, which is part of why she lies awake at 3 a.m. Now watch what the war does on top of that. Aggressive dieting and grinding workouts are themselves potent cortisol triggers, so they pile still more load onto an already-dysregulated system, which deepens the glucocorticoid resistance, which weakens the cortisol brake further, which lets the inflammation run harder. The war is not neutral. It actively props the doors open and wears the brakes down. Relief begins by laying it down, and doing these five things instead.

Restores the muscle brake, and retrains the pain system

1Move the joint, gently and on purpose

This is the hardest one to believe because it runs straight against instinct. When a joint hurts, every cell in you says stop moving it, protect it, rest it. That instinct is not foolish. It is ancient and usually correct. For most of human history, pain meant a fresh injury that needed stillness to heal, so your brain reads joint pain as a danger signal that says if you keep moving, you will damage this further.

But in this situation, the instinct is misreading the message. This pain is not a fresh tear that rest will mend. It is inflammation in a sensitized joint, and here is the trap. When you stop moving to protect the joint, three things happen, all of them bad. The muscle around it weakens and stops sending its anti-inflammatory signals, so a brake comes off. The joint itself stiffens and loses the very movement that feeds cartilage, which has no blood supply of its own and is nourished only by being loaded and unloaded like a sponge. And the nervous system, now braced and vigilant, flinching in anticipation of pain with every step, grows more sensitized, not less, so the pain climbs. The fear of movement, however reasonable it feels, quietly makes all of it worse. Researchers who study chronic pain have a name for this trap, the fear-avoidance cycle, and it is one of the most powerful engines of persistent pain there is.

Gentle, progressive movement breaks that cycle from every direction at once. It rebuilds the muscle that stabilizes the joint and restores its anti-inflammatory signals, and in controlled studies, progressive strength training measurably lowers those alarm cytokines, IL-6 and TNF-alpha. It nourishes the cartilage through loading. And it teaches a sensitized nervous system that the movement is not the threat it has been braced for, gradually turning the pain volume back down. The rule is not no pain, no gain, and it is not rest until it stops hurting. It is this: start smaller than you think you need to, move consistently, add a little at a time, and let both the tissue and the nervous system relearn that motion is not damage. You are not risking the joint by moving it well. You are reclaiming it.

Restores the nightly reset

2Rebuild your sleep

Deep sleep is the body’s repair shift, the hours when much of the day’s inflammation is cleared and tissue maintenance happens. When sleep breaks, that nightly stand-down never comes, and the loss also loosens the gut lining and raises stress, propping open doors on the other side. This is why sleep is not a luxury here. It is a brake and a repair window in one. Protecting it, through morning light, a steady routine, a cool dark room, and by treating the causes of 3 a.m. waking rather than gritting through them, is one of the highest-value things a midlife woman can do for her joints. For many women in perimenopause the disrupted sleep has a specific hormonal driver, which points straight toward the hormone conversation below.

Closes the diet and gut doors

3Feed the fire less

You cannot supplement your way out of an inflammatory diet, and you do not need to eat flawlessly to change the signal. A diet high in sugar and heavily processed food does two things at once. It trips the danger sensors directly, and it loosens the gut lining, holding two doors open together. A whole-food, Mediterranean-style pattern, rich in omega-3 fats, olive oil, vegetables, and deeply colored plants, does the reverse, calming the signal and helping the gut wall knit back together. Adequate protein matters especially in midlife because it is the raw material for the muscle you are rebuilding. Vitamin D sufficiency earns its place too. None of this is about shrinking. It is about closing doors.

Restores the cortisol brake

4Bring down the cortisol load

Recall the most important brake, and how it fails. Cortisol is meant to switch inflammation off, but when it stays chronically high, the immune cells go deaf to it, glucocorticoid resistance, and the brake stops working. In midlife this matters doubly. The loss of estrogen has already destabilized the cortisol rhythm before the woman lifts a finger. So the goal is not to grit through more stress. It is to genuinely lower the chronic load, so the rhythm can settle and the brake can regain its grip. That means real recovery, treated as a medical intervention rather than a reward: the daily walk, the exhale that lengthens naturally over a few quiet minutes, unhurried meals, stretches of time in which the nervous system is not braced for the next demand, and the boundaries that stop the stress leaks at the source. These are not soft suggestions. Lowering the cortisol load is how you hand the body back its most powerful anti-inflammatory brake.

Restores the hormonal brakes

5Have the whole hormone conversation, not just the estrogen one

For many women, restoring the missing hormones is the most direct lever of all. Those hormones were holding several brakes at once. This is a conversation to have with a menopause-literate or bioidentical-hormone clinician who knows your history, not a decision to make from a blog post. But you should know what is actually on the table because most women are never told.

Estrogen is the one with the strongest evidence for this specific problem. A large 2025 review of nearly 4 million women found lower rates of musculoskeletal pain among hormone therapy users, and Women’s Health Initiative data showed estrogen users better protected from joint pain and joint replacement. Replacing estrogen restores the biggest brake, the gut-tightening, cytokine-quieting, joint-maintaining hormone this entire article has been about.

Progesterone deserves its own mention, especially for the woman lying awake at 3 a.m. Taken as oral micronized progesterone at bedtime, it is converted in the brain into a calming compound that acts on the same receptors as anti-anxiety medication, and in randomized trials it improves deep sleep and lowers anxiety, without the dependence of sleeping pills. It also helps support the gut lining. For broken sleep and the anxiety riding alongside it, this is a genuinely useful and badly under-discussed tool.

Testosterone and DHEA are the piece almost no one mentions to women, and the emerging picture is worth understanding. Testosterone, which women make and lose too, is important for building and preserving the lean muscle that stabilizes and protects joints, and the early clinical data are promising. In one 2024 cohort of nearly 800 women already on hormone therapy, a majority reported meaningful improvement in muscle and joint pain within months of adding testosterone. DHEA is an adrenal hormone the body uses as a raw material to make testosterone, which is why some clinicians check DHEA levels and keep testosterone optimized as part of a muscle-preservation and pain strategy. Two honest caveats belong here. The evidence for testosterone in women is strongest for muscle and is still emerging for joint pain specifically, and in most places testosterone for women is prescribed off-label and guided by blood work. That is precisely why it belongs in a real conversation with a knowledgeable clinician, where your own levels steer the decision. The point is only this: the hormone conversation is far bigger than estrogen alone, and you are allowed to ask about all of it.

Your body did not betray you

You were never simply getting old. You were never imagining it. Over a handful of years, your body lost the hormones that had been holding a whole set of brakes, and the inflammatory alarm they kept quiet for decades began to ring. At the same time, the immune system that should have resolved that inflammation and repaired the tissue was itself worn down, so the damage built while the healing lagged. None of that was your fault, and none of it was a failure of will. It was physiology, and physiology can be answered.

Here is what you now understand, and could explain to any woman who needs it. The pain is inflammation in a sensitized joint. The inflammation runs because doors are open and brakes have failed. The brakes can be restored, by moving, by sleeping, by eating to close the doors, by lowering the true stress load, and, for many women, by replacing the hormones that were holding them. Do that, and you are not forcing your body to heal. You are rebuilding the conditions under which it heals itself. That is the entire premise, and it is exactly where the work begins.
