Key Takeaways
- Polymyalgia rheumatica symptoms center on pain and stiffness in both shoulders and both hips, worst in the morning and lasting 45 minutes or longer.
- PMR comes on over days to weeks, not years, and almost always affects adults over 50, most often in their late 60s and 70s.
- The exact causes of polymyalgia rheumatica are unknown, but it involves an abnormal immune response, not injury or overuse, and it is not contagious.
- Roughly 10 to 20 percent of people with PMR develop giant cell arteritis, which can cause sudden vision loss; new headache, scalp tenderness, jaw pain, or vision changes need urgent care.
- Low-dose prednisone usually brings dramatic relief within days, and that rapid response is itself part of the diagnosis.
- PACT Rheumatology in Hamden, Guilford, and Orange diagnoses and manages PMR and related conditions for patients in Connecticut.
You woke up one morning and couldn’t lift your arms to brush your hair. Getting out of a chair takes a plan. It’s both shoulders, maybe both hips, and it came on fast. Your first guess was a bad night’s sleep, then a rotator cuff problem, then “I guess this is what 68 feels like.”
It may be none of those. Polymyalgia rheumatica (PMR) is one of the most common inflammatory conditions in adults over 50, and one of the most frequently mistaken for ordinary arthritis or simply getting older. According to a clinical review on the National Library of Medicine’s StatPearls, PMR ranks as the second most common inflammatory rheumatic disease after rheumatoid arthritis in some populations, with 58 to 96 new cases per 100,000 adults over 50 each year. It is also one of the most treatable, once someone names it.
In this post, you’ll learn:
- What polymyalgia rheumatica is and who it affects
- The symptoms that set PMR apart from arthritis and injury
- What causes PMR, and what doesn’t
- The giant cell arteritis warning signs every PMR patient should know
- How a rheumatologist diagnoses and treats it, and when to make the appointment
What Is Polymyalgia Rheumatica?
Polymyalgia rheumatica (PMR) is an inflammatory condition that causes pain and stiffness in the shoulders, neck, upper arms, hips, and thighs, almost always on both sides of the body. It is most common in adults over 50, with most diagnoses made in the late 60s and 70s, and it affects women more often than men.
Two features make PMR distinctive among the conditions it gets confused with:
- It is symmetrical. Both shoulders, both hips, or both. Rotator cuff tears and hip osteoarthritis usually hit one side.
- It responds dramatically to low-dose corticosteroids. Many patients feel markedly better within days of starting prednisone, which no injury or osteoarthritis does.
Despite the name (polymyalgia means “many muscle pains”), PMR is not a muscle disease. The inflammation sits in the joint linings and the fluid-filled bursae around them.
Polymyalgia Rheumatica Symptoms
This is the pattern a rheumatologist listens for.
Pain and Stiffness in Both Shoulders and Hips
This is the hallmark. Pain and stiffness in both shoulders and/or both hips, not just one. Patients describe being unable to raise their arms above shoulder height, struggling to pull on a coat, or needing to push off the armrests to stand.
Severe Morning Stiffness
Stiffness is worst on waking or after sitting still, and it lasts 45 minutes or more, often over an hour. Osteoarthritis stiffness tends to ease within 15 to 30 minutes. PMR stiffness lingers through breakfast.
Aching That Spreads Into the Neck, Upper Arms, and Thighs
The discomfort rarely stays in the joint itself. It radiates into the surrounding muscles, which is why so many people assume they strained something.
Fatigue, Low-Grade Fever, and Feeling Unwell
Profound tiredness, a mild fever, loss of appetite, unintentional weight loss, and a general sense of being ill often ride alongside the stiffness. These are signs of body-wide inflammation, not of aging.
Rapid Onset
PMR develops over days to a couple of weeks. Osteoarthritis takes years. Most PMR patients can tell you roughly when it started, and many remember the specific week.
How PMR Compares to the Conditions It’s Mistaken For
| Factor | Polymyalgia rheumatica | Rheumatoid arthritis | Osteoarthritis |
| Typical age | Over 50, peak late 60s to 70s | Any age, often 30s to 60s | Over 50, rises with age |
| Where it hurts | Shoulders, hips, neck, thighs (both sides) | Small joints of hands, wrists, feet (both sides) | Knees, hips, hands, spine (often one side) |
| Onset | Days to weeks | Weeks to months | Years |
| Morning stiffness | 45 minutes or longer | Over an hour | Under 30 minutes |
| Joint swelling | Uncommon | Common, visible | Bony enlargement |
| Response to low-dose prednisone | Dramatic, within days | Partial | Minimal |
What Causes Polymyalgia Rheumatica?
The exact cause of PMR is not fully understood. The leading explanation is an abnormal immune response: the immune system mistakenly attacks the lining of the joints and the nearby bursae, producing inflammation. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), inflammation drives the condition, but the trigger is still unknown.
Factors that appear to contribute:
- Age. PMR almost exclusively affects adults over 50, and risk rises into the 80s.
- Genetics. Certain HLA gene variants are associated with higher risk, though the link is inconsistent across populations.
- Environmental triggers. Some studies suggest viral infections may set off the immune response in susceptible people.
- Ancestry. PMR is more common in people of Northern European descent, though it occurs in every group.
Equally important is what does not cause it. PMR is not caused by overuse, injury, or poor posture, and it is not contagious.
PMR and Giant Cell Arteritis: What Every Patient Needs to Know
Giant cell arteritis (GCA) is inflammation of the large blood vessels, particularly the arteries in the head and neck. It travels with PMR often enough that every PMR patient should know its warning signs. NIAMS reports that about 10 percent of people with PMR also have GCA, and the StatPearls review puts the figure closer to 20 percent over time. Roughly half of people with GCA have PMR.
GCA matters because, untreated, it can cause sudden and permanent vision loss. Seek urgent evaluation, the same day, for any of the following, especially if you already have or suspect PMR:
- A new or unusual headache, often at the temples
- Scalp tenderness (it hurts to brush your hair or rest your head on a pillow)
- Jaw pain or fatigue when chewing
- Any change in vision: blurring, double vision, or loss of vision in one eye, even briefly
This is a reason to know the list, not a reason for daily worry. GCA is very treatable when caught early, using the same family of medication as PMR at a higher dose.
How Is PMR Diagnosed and Treated?
There is no single test for PMR. A rheumatologist diagnoses PMR by combining three things: the symptom pattern described above, blood tests showing elevated inflammatory markers (ESR and CRP), and the response to corticosteroids. The American College of Rheumatology notes that not everyone with PMR has elevated markers, which is why a specialist who sees it regularly makes the diagnosis.
The workup also rules out conditions that can mimic PMR:
- Rheumatoid arthritis and other inflammatory arthritis
- Lupus and related autoimmune diseases
- Thyroid disorders and infection
- Certain cancers, which can present with similar body-wide symptoms
Treatment is low-dose prednisone, typically 10 to 15 mg per day to start. Improvement is usually dramatic within days, and that rapid response helps confirm the diagnosis. The dose is then tapered gradually over one to two years, sometimes longer. Relapses are common when steroids are reduced too quickly, so the taper is slow and the follow-up is regular, with monitoring of bone density and blood sugar along the way.
When to See a Rheumatologist
Any adult over 50 with new stiffness in both shoulders or both hips that lasts 45 minutes or more in the morning should be evaluated, especially if fatigue, weight loss, or elevated inflammatory markers come with it. Primary care is a reasonable first call, but PMR is a pattern-recognition diagnosis, and rheumatologists do this every day, separating it from its look-alikes.
Don’t wait if:
- Stiffness has lasted more than two weeks with no clear injury
- Over-the-counter pain relievers barely touch it
- You’ve lost weight or appetite without trying
- You have any of the giant cell arteritis warning signs above (seek same-day care)

FAQs: Polymyalgia Rheumatica
What are the symptoms of polymyalgia rheumatica?
The main polymyalgia rheumatica symptoms are pain and stiffness in both shoulders and both hips, worst in the morning and lasting 45 minutes or longer. The aching often spreads into the neck, upper arms, and thighs. Fatigue, low-grade fever, loss of appetite, and unintentional weight loss are common, and symptoms typically develop over days to weeks.
What triggers PMR?
The exact trigger is unknown. PMR involves an abnormal immune response that inflames the lining of the joints and nearby bursae. Age over 50, certain HLA gene variants, Northern European ancestry, and possibly viral infections appear to raise risk. PMR is not caused by injury, overuse, or activity, and it is not contagious.
What is the difference between PMR and rheumatoid arthritis?
Polymyalgia rheumatica affects the shoulders, hips, neck, and thighs in adults over 50, comes on over days to weeks, rarely causes visible joint swelling, and improves dramatically with low-dose prednisone. Rheumatoid arthritis can start at any age, targets the small joints of the hands, wrists, and feet, causes visible swelling, and needs disease-modifying medications rather than steroids alone.
What is the treatment for polymyalgia rheumatica?
Polymyalgia rheumatica treatment is low-dose prednisone, usually 10 to 15 mg per day to start, which typically relieves pain and stiffness within days. The dose is then tapered slowly over one to two years, sometimes longer. Relapses can occur if the taper is too fast, so regular follow-up with a rheumatologist is part of treatment.
Is polymyalgia rheumatica serious?
PMR itself is not life-threatening and responds well to treatment, but it is serious in two ways. Untreated, it can be disabling. And roughly 10 to 20 percent of people with PMR develop giant cell arteritis, which can cause permanent vision loss if not treated promptly. New headache, scalp tenderness, jaw pain with chewing, or vision changes need same-day medical attention.
Does polymyalgia rheumatica go away?
For most people, yes. PMR typically runs its course over one to three years with corticosteroid treatment, and many patients eventually stop medication entirely. Some experience relapses that require restarting or increasing prednisone, and a smaller number need longer-term low-dose treatment. A rheumatologist manages the taper to minimize both relapses and steroid side effects.
