Polymyalgia Rheumatica -rü-ˈmat-i-kə

Polymyalgia rheumatica involves inflammation of the lining of joints, causing severe pain and stiffness in the muscles of the neck, back, shoulders, and hips.

  • The cause is unknown.

  • The neck, back, shoulders, and hips feel stiff and painful.

  • Blood tests and sometimes biopsy of a muscle help doctors make the diagnosis.

  • Most people improve dramatically when they take prednisone, a corticosteroid.

Polymyalgia rheumatica occurs in people over age 55. Women are affected more often than men. Its cause is unknown. Polymyalgia rheumatica may occur before, after, or at the same time as giant cell (temporal) arteritis. Some experts think that the two disorders are variations of the same abnormal process. Polymyalgia rheumatica seems to be more common.


Symptoms may develop suddenly or gradually. Severe pain and stiffness occur in the neck, shoulders, upper and lower back, and hips. The stiffness and discomfort are worse in the morning and after periods of inactivity and are occasionally severe enough to prevent people from getting out of bed and from doing simple activities. People may feel weak, but the muscles are not damaged or weak. People may also have a fever, feel generally unwell or depressed, and lose weight unintentionally.

Some people with polymyalgia rheumatica also have symptoms of giant cell arteritis, which can lead to blindness. Some people have mild arthritis, but if the arthritis is severe or is the main symptom, the diagnosis is more likely to be rheumatoid arthritis.


  • Physical examination

  • Blood tests

  • Response to corticosteroids

Doctors base the diagnosis on symptoms and results of a physical examination and blood tests as well as the response to corticosteroids (most people with polymyalgia rheumatica feel much better very quickly when treated with corticosteroids). Blood tests usually include the following:

  • Erythrocyte sedimentation rate (ESR), C-reactive protein levels, or both: In people with polymyalgia rheumatica, results of both tests are usually very high, indicating active inflammation.

  • Blood count: This test is done to check for anemia.

  • Thyroid-stimulating hormone: This test is done to rule out hypothyroidism, which can cause weakness and sometimes pain of the shoulder and hip muscles.

  • Creatine kinase: This test is done to check for muscle tissue damage (myopathy), which can cause weakness and pain of the shoulder and hip muscles. If the level of creatine kinase in the blood is elevated, muscle damage is likely. In people with polymyalgia rheumatica, muscle damage is absent, so the creatine kinase level is normal.

  • Rheumatoid factor and anticyclic citrullinated peptide antibodies testing: These antibodies are present in up to 80% of people with rheumatoid arthritis but not in those with polymyalgia rheumatica. This test helps doctors distinguish between the two.


  • Low-dose prednisone

  • Low-dose aspirin

Taking a low dose of prednisone, a corticosteroid, usually causes dramatic improvement. If people also have giant cell arteritis, a higher dose is prescribed to reduce the risk of blindness. As the symptoms subside, the dose is gradually reduced (tapered) to the lowest effective dose. Many people can stop taking prednisone in less than 1 year. However, some people need to take a low dose for several years.

Corticosteroids commonly cause side effects in older people (see Spotlight on Aging: Giant Cell Arteritis and Polymyalgia Rheumatica).

Aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) can help relieve pain but are usually less effective than prednisone. People usually take a low dose of aspirin daily to help prevent complications of giant cell arteritis, such as strokes, heart attacks, or vision loss.

Giant cell arteritis may develop at the start of polymyalgia rheumatica or much later, sometimes even after people appear cured of the disorder. Therefore, all people should immediately tell their doctor if they have headache, muscle pain during chewing, unusual cramping or fatigue of the arms or legs with exercise, or vision problems.
