It starts somewhere small and unexplained. Hands stiff in the morning. A knee that objects to the stairs. A heel that hurts for the first twenty steps out of bed. A shoulder that will not go above your head any more and you cannot remember hurting it.
Each one gets treated as its own small problem, filed under getting older, chased individually across a year of appointments. They are very often the same problem.
Why joints start hurting
Estrogen turns out to be doing a lot of quiet structural work.
It has an anti-inflammatory effect, dampening inflammatory signalling throughout the body. It supports cartilage maintenance. It is involved in the health of the synovium, the lining that produces the fluid joints move in. And it affects collagen, which is the raw material of tendons and ligaments as well as skin.
When estrogen becomes erratic, all four of those get less reliable at once. The result is joints that are stiffer, tendons that are less tolerant of load, and a body-wide inflammatory tone that is slightly higher than it was. Nothing is injured. Everything aches.
The pattern is characteristic enough to be worth memorising:
- Worst first thing in the morning
- Eases within about half an hour of moving
- Several joints at once rather than one
- Hands, knees, hips, shoulders, feet
- Varies with the cycle, and with how you slept
- No injury that explains it
The three nobody connects
Frozen shoulder. Gradual loss of shoulder movement, often painful at night, typically without any injury. It has a marked concentration in women between about forty and sixty — a pattern that is difficult to explain without hormonal involvement, and an active question in the research. The reason it matters here is practical: almost nobody connects it to perimenopause, so it gets managed as an isolated shoulder problem while everything else goes unexamined. If you have a stiffening shoulder and any two other things from this site, say so at the appointment.
Plantar heel pain. Pain under the heel that is worst for the first steps of the morning and after sitting. It was one of the most common answers in the threads asking what nobody had warned women about, far out of proportion to how often it comes up elsewhere.
Hand and wrist tendon problems. Trigger finger, and pain at the base of the thumb and the thumb-side wrist. Both cluster in women of this age. Both get attributed to typing.
When three of these arrive within two years of each other, in a woman in her mid-forties whose periods have also changed, the common factor is worth raising.
What actually helps
Move it — the instinct to rest is usually wrong
For the ordinary aching of this stage, movement is the treatment. Joints are fed by movement; cartilage has no blood supply of its own and depends on loading and unloading to exchange nutrients. A body that hurts and therefore moves less gets stiffer, which hurts more.
Daily, gentle, non-negotiable. Ten minutes of walking before you decide how the day is going to go.
Tendons want load, not protection
This is the single most useful and most counter-intuitive thing in this article. A painful tendon does not want rest — it wants progressive, controlled load, applied slowly and heavily enough to stimulate remodelling. Prolonged rest weakens it, and the weakened tendon hurts more when you return.
The skill is in the dose. Slow, heavy, controlled repetitions, staying within a tolerable level of discomfort, progressed weekly. Pain during the exercise up to a modest level is acceptable; pain that is worse the next morning means the dose was too high.
This is precisely the kind of judgement a plan downloaded from the internet cannot make for you, and the reason so many women bounce between resting until it stiffens and charging back in until it flares.
Build strength around the joint
Strong muscle takes load off the joint it crosses. Strength training is the best-evidenced intervention for knee and hip pain of the ordinary kind, and it also addresses the muscle loss that accelerates through this stage, and the bone loss, and the sleep. It is the single highest-return thing available and the least likely to be recommended to a woman who has mentioned aching joints.
Start lighter than you think and progress every week.
Eat enough protein
Collagen synthesis needs amino acids, and the woman most likely to be short of them is the one eating lightly to manage her weight. Under-eating protein while trying to repair tendons is working against yourself in two directions at once.
The ordinary levers still apply
Sleep is when tissue repair happens, and broken sleep raises pain sensitivity measurably. Vitamin D is worth checking. Carrying less weight reduces load through knees and hips, though muscle is usually the bigger lever than the scale. Alcohol is inflammatory and wrecks the sleep.
What needs ruling out
This is the section that matters most, because two conditions that present almost identically also rise sharply in women at this exact age.
Inflammatory arthritis — rheumatoid arthritis in particular — typically looks like: morning stiffness lasting well over an hour, joints that are visibly swollen and warm, a symmetrical pattern in the small joints of the hands and feet, and fatigue or feeling generally unwell alongside it. It peaks in women in their forties and fifties. Early treatment substantially changes the long-term outcome, which is why assuming hormones is a costly mistake here.
Thyroid disease produces aches, stiffness and exhaustion, and is very common in this group.
Also worth checking: vitamin D, and a full blood count with inflammatory markers.
See someone promptly for any of: a single hot, swollen, very painful joint; joint pain with fever or feeling unwell; a joint that gives way or locks; pain that wakes you every night; any significant loss of movement in a joint; or pain following a fall.
Why this one is worth taking seriously
Joint pain sounds like the least dramatic thing on this site. It is the one most likely to stop you doing the thing that helps everything else.
A woman who stops training because her knees hurt loses muscle and bone at the fastest-losing stage of her life, sleeps worse, and arrives on the other side of this in materially worse shape than she needed to be. The aching is uncomfortable. Being talked out of strength training by it is the actual cost.
