Polymyalgia rheumatica: symptoms, treatment, and when to worry
Last updated September 3, 2026.
Polymyalgia rheumatica (PMR) is an inflammatory condition causing severe stiffness and aching around the shoulders, neck, and hips, worst in the morning, almost always in people over 50. The signature is being unable to lift your arms to dress or turn over in bed, then loosening as the day goes on. It responds dramatically to steroids, usually within days, and it is linked to a serious cousin, giant cell arteritis, that must not be missed.
What does it feel like?
The onset can be abrupt, sometimes over days: deep aching and stiffness across both shoulders and often the hips, worst on waking, lasting more than 45 minutes, easing with movement. Dressing, rising from chairs, and rolling in bed become the hard tasks. Fatigue, low mood, mild fever, and weight loss can accompany. Blood tests show raised inflammation markers, and there is no single definitive test, so the picture, the age, the markers, and the rapid steroid response together make the diagnosis.
What actually helps?
- Steroid tablets are the treatment: a moderate starting dose of prednisolone typically transforms symptoms within days, and that dramatic response is itself diagnostic evidence. The dose then tapers slowly over many months to two years or more.
- Taper slowly, expect bumps: dropping the dose too fast flares the symptoms; flares are common and managed by stepping back up briefly. Coming off steroids entirely takes patience.
- Bone protection during treatment: long steroid courses thin bones, so calcium, vitamin D, and often bone-protecting medication accompany treatment, with a bone density scan.
- Know the steroid side effects: weight gain, raised blood sugar, easy bruising, and infection risk are monitored at reviews, and most are dose-dependent and reversible as the dose falls.
- Learn the giant cell arteritis warnings: every PMR patient should know them cold (see below), because the two conditions overlap.
When is it an emergency?
The emergency is giant cell arteritis arriving: a new severe headache, scalp tenderness (pain brushing hair), pain in the jaw when chewing, and any visual symptom, double vision, blur, or a shadow, in someone over 50 is same-day urgent care, because untreated giant cell arteritis can take vision permanently and steroids must start immediately. That warning applies doubly to anyone with PMR. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
How is polymyalgia rheumatica diagnosed?
There is no single test, so the diagnosis is a pattern: over 50, new bilateral shoulder and hip girdle aching, morning stiffness beyond 45 minutes, raised inflammation markers (ESR and CRP) on blood tests, exclusion of mimics like rheumatoid arthritis, and, tellingly, a dramatic response to a moderate steroid dose within days. Ultrasound of the shoulders can add supporting evidence. When that pattern lines up, the diagnosis is solid.
How quickly do steroids work for PMR?
Dramatically fast, often within 24 to 72 hours, and that speed is part of the diagnosis. A patient who cannot lift their arms on Monday is often dressing normally by Friday. The response is also the tapering trap: feeling cured tempts early stopping, and PMR almost always flares if steroids are rushed. The standard course is many months of slow tapering, with flares managed by brief dose increases.
What is the link between PMR and giant cell arteritis?
They are siblings: the same inflammatory process in different territory. PMR inflames the shoulder and hip girdles; giant cell arteritis inflames arteries, including those supplying the eye. A significant share of PMR patients develop giant cell arteritis, and vice versa. The PMR patient instruction is simple and serious: new headache, scalp tenderness, jaw pain on chewing, or any visual symptom means same-day care, because vision loss there is preventable and permanent.
What are the side effects of long-term steroids?
The honest list: weight gain and a rounder face, raised blood sugar, blood pressure creep, easy bruising and thin skin, infection susceptibility, bone thinning, mood effects, and sleep disturbance. They are dose-dependent, which is why the taper exists, and the important ones are actively managed: bone protection is routine, and bloods and pressure are monitored. For PMR there is no equally effective alternative, so the strategy is the lowest effective dose for the shortest workable time.
How long does polymyalgia rheumatica last?
Typically one to two years of steroid treatment, sometimes longer, with most people eventually coming off steroids entirely and staying well. Relapses during the taper are common and not failure. A minority have a longer course. The honest framing: PMR is very treatable and usually self-limiting over years, but it runs on its own clock, and racing the taper is the one reliably losing strategy.
Is PMR the same as fibromyalgia?
No, and the distinction changes treatment. PMR: over 50, inflammatory blood markers up, morning-dominant shoulder and hip girdle stiffness, and a rapid, near-complete response to steroids. Fibromyalgia: any age, normal inflammation markers, widespread pain with tender points, fatigue and unrefreshing sleep, and no steroid response. They feel similar from the inside and are completely different conditions from the blood test outward, which is why the markers get checked before steroids start.
