Polymyalgia Rheumatica: Sudden Shoulder and Hip Stiffness

TL;DR: Polymyalgia rheumatica (PMR) is an inflammatory condition in adults over 50 that brings on pain and stiffness in the shoulders and hips, worst in the morning and often arriving over days rather than years. Blood work usually shows a high CRP and ESR, and the response to a low dose of steroids is quick enough to be part of the diagnosis. PMR is closely tied to giant cell arteritis, a blood-vessel inflammation that needs urgent care, so knowing the warning signs matters. Once PMR is named, it is very treatable.

If you are in your 60s or 70s and woke up one morning barely able to lift your arms to wash your hair or get dressed, stiff through the shoulders and hips in a way that eases as the day goes on, and someone has waved it off as "just getting older," I want you to know that pattern has a name. Aging is gradual. A stiffness that comes on over a week or two, paired with a high inflammation marker, is usually something specific and treatable rather than the calendar. Understanding what it is turns a frightening loss of function into a manageable diagnosis.

What is polymyalgia rheumatica?

Polymyalgia rheumatica is an inflammatory condition that causes aching and stiffness in the large muscle groups around the shoulders and hips, the areas doctors call the shoulder and pelvic girdles.¹ It almost always begins after age 50 and becomes more common with each decade after that, affecting women more often than men and people of Northern European ancestry more than others.

The hallmark is morning stiffness that is deep and limiting, often lasting more than 45 minutes and sometimes the whole morning, making it hard to rise from a chair, lift the arms overhead, or turn over in bed. The onset is usually fairly abrupt, developing over days to a couple of weeks, and it is typically symmetric, hitting both shoulders or both hips at once. Many people also feel a general unwellness: low-grade fatigue, a poor appetite, or a low fever. The pain comes from inflammation in the tissues around the joints rather than damage to the joints themselves, which is why PMR does not deform the joints the way some forms of arthritis do.

How is polymyalgia rheumatica diagnosed?

Polymyalgia rheumatica is diagnosed by putting together the clinical picture, the inflammation markers, and the response to treatment, because no single test proves it on its own. The clinical picture is the starting point: an adult over 50 with new, symmetric shoulder and hip girdle pain and prolonged morning stiffness.

Blood work usually shows a high CRP and a high erythrocyte sedimentation rate (ESR), the two inflammation markers, and this is often where PMR first announces itself, since a strikingly high CRP or ESR in an older adult with girdle stiffness is a strong clue. A small share of people with PMR have a normal ESR, so a normal marker does not fully rule it out when the story fits. The other diagnostic feature is the response to a low dose of glucocorticoid: PMR tends to improve dramatically within a few days of starting steroids, and that quick, near-complete relief helps confirm the diagnosis. Before settling on PMR, though, the workup rules out the conditions that can look like it, including rheumatoid arthritis, thyroid disease, infection, statin-related muscle aches, and, less often, cancer, which is why a careful evaluation matters more than a single lab value. Our guide on the musculoskeletal syndrome of menopause covers a different girdle-pain pattern that can be mistaken for it.

What is the link between PMR and giant cell arteritis?

The link between polymyalgia rheumatica and giant cell arteritis (GCA) is close and clinically important. Giant cell arteritis is inflammation of medium and large arteries, often the ones supplying the scalp, jaw, and eyes, and it shares the same underlying tendency toward inflammation that drives PMR.³ Roughly 15% of people with PMR develop GCA, and many people with GCA also have PMR symptoms, so the two are treated as two ends of one disease spectrum.

The reason this matters is that giant cell arteritis is a medical urgency: untreated, the inflammation can cut off blood flow to the eye and cause sudden, permanent vision loss. The good news is that the warning signs are knowable, and catching them early allows prompt treatment that protects vision. Worth acting on quickly are a new or changed headache, tenderness of the scalp or temples, pain or fatigue in the jaw while chewing, and any visual change such as blurring, double vision, or a brief loss of sight in one eye. Anyone with polymyalgia rheumatica who develops these should be evaluated the same day rather than waiting, since starting treatment early is what prevents the serious outcomes.

How is polymyalgia rheumatica treated?

Polymyalgia rheumatica is treated with a low dose of glucocorticoid, usually prednisone, and the improvement is often quick and substantial.² A typical starting dose brings relief within days, restoring the ability to move and dress and sleep, which is a welcome change after weeks of stiffness. The art is in what comes next: the dose is tapered down slowly over a year or two, guided by symptoms and inflammation markers, because reducing it too fast is the most common reason PMR flares back.

Because steroids carry their own costs over time, on bone density, blood sugar, sleep, and mood, treatment pairs the medication with protection: bone health support, monitoring of glucose and blood pressure, and attention to sleep. When PMR keeps flaring on tapering, or when someone cannot tolerate steroids well, a steroid-sparing medication such as methotrexate or an interleukin-6 blocker can be added to bring the steroid dose down. Throughout, the treatment stays alert for any sign of giant cell arteritis, which needs higher-dose, more urgent therapy if it appears. Most people with PMR do well, regain their function, and eventually come off treatment.

How does Fishtown Medicine approach polymyalgia rheumatica?

At Fishtown Medicine, polymyalgia rheumatica is approached as a treatable inflammatory condition that deserves a precise diagnosis rather than a shrug about aging. That starts with taking new girdle stiffness in an older adult seriously, pairing the clinical picture with CRP and ESR, and ruling out the mimics through the Five Foundations lens and the right labs, so the diagnosis is sound before steroids begin. Because a quick steroid response is part of the diagnosis, we make that decision thoughtfully, in coordination with rheumatology when the picture is complex.

Once the diagnosis is set, the ongoing work is the careful part: guiding a slow, symptom-led taper, protecting bone, blood sugar, and sleep against the effects of steroids, and staying watchful for any warning sign of giant cell arteritis. For anything that calls for a procedure, such as a temporal artery biopsy to confirm giant cell arteritis, we bring in highly qualified specialists who are in network for you, and we coordinate closely with rheumatology and, when eye symptoms arise, with ophthalmology. We compare notes across a network of specialists so the answer is right and the urgent pieces move fast, which is where this kind of tight coordination protects both function and vision. Whether you are nearby in Fishtown or Rittenhouse, or coming across the Ben Franklin Bridge from Cherry Hill or Moorestown, the aim is to name it early, treat it well, and get you moving comfortably again.

Guidance from the Clinic

"When someone in their 60s or 70s tells me they suddenly can't lift their arms to get dressed and they're stiff for hours every morning, I'm thinking about polymyalgia rheumatica before I'm thinking about age. It's one of the conditions where the treatment works so well that the response helps confirm it. The part I never let slide is the giant cell arteritis piece, because the headache or the jaw pain or the vision change is what we can't wait on. Named early, this is a very manageable diagnosis."
