Summary

  • Symptoms of polymyalgia rheumatica include severe muscle aches and stiffness, unexplained weight loss and fatigue.
  • The cause of polymyalgia rheumatica is unknown, but genetics and environmental factors are believed to play a role.
  • Approximately one in five people with polymyalgia rheumatica experience giant cell arteritis (inflammation of the arteries). If left untreated, giant cell arteritis can cause blindness in one or both eyes.

Polymyalgia rheumatica is a condition causing pain and stiffness in older adults. Typical symptoms include severe and painful muscle aches and stiffness, particularly affecting the neck, shoulders and thighs. The onset is usually sudden. 

People aged 50 years and over are most commonly affected by polymyalgia rheumatica. The average age of diagnosis is 70 years. Polymyalgia rheumatica is common and very treatable.

Polymyalgia rheumatica should not be confused with fibromyalgia – a condition that causes pain and muscle stiffness, but does not cause inflammation.

Symptoms of polymyalgia rheumatica

Symptoms of polymyalgia rheumatica can include:

  • muscle pain and stiffness, particularly in the neck, shoulders, hips and upper arms
  • stiffness that worsens after resting – for example, symptoms may be most severe when getting up in the morning
  • fatigue
  • difficulty sleeping
  • difficulty raising arms above shoulder height
  • unexplained weight loss.

Polymyalgia rheumatica and giant cell arteritis

Approximately one in five people with polymyalgia rheumatica experience giant cell arteritis (also known as temporal arteritis). Giant cell arteritis involves painful inflammation of the blood vessels (arteries) of the skull. The temples are tender to touch and chewing may cause some pain in the side of your face. 

Giant cell arteritis can cause damage to the arteries of the eye, which can lead to blindness. This damage can be prevented if giant cell arteritis is treated promptly. 

See your doctor immediately if you experience headaches, blurred or double vision, if your temples are tender to touch and if chewing causes pain in the side of your face.

Cause of polymyalgia rheumatica

Polymyalgia rheumatica produces inflammation and swelling in the larger joints of the body, such as the shoulders and hips, and in the tissues around these joints. The inflammation is due to the immune system attacking the membranes lining the joint (synovium), but the reason for this is unknown. Genetics and environmental factors (such as infections) are believed to play a role.

Risk factors for polymyalgia rheumatica

Risk factors for polymyalgia rheumatica include:

  • Advancing age - the condition is more common in people aged 50 years and over, with most people diagnosed at around 70 years.
  • Gender - women are more likely to develop the condition than men.
  • Race - Caucasian (white) people are most susceptible.

Diagnosis of polymyalgia rheumatica

No single test can diagnose polymyalgia rheumatica, so your doctor will make a diagnosis based on several factors. These include your medical history, a physical examination, tests that measure the levels of inflammation markers in the blood, and tests to rule out other possible causes. 

Tests to confirm or exclude polymyalgia rheumatica may include:

  • blood tests to check for inflammation in the body by measuring the erythrocyte sedimentation rate or the level of C-reactive protein
  • blood tests to rule out other conditions
  • tests to check for giant cell arteritis - for example, biopsy of the temple arteries.

Treatment for polymyalgia rheumatica

Most people with polymyalgia rheumatica will be treated with oral corticosteroid medication. The amount prescribed will depend on the situation. A higher dose will be prescribed in more severe conditions and when giant cell arteritis is present. 

The aim of treatment for polymyalgia rheumatica is to relieve the symptoms and slowly reduce the medication dose to the lowest possible amount without the return of symptoms.

Complications of oral corticosteroids

Long-term use of oral corticosteroids can cause unwanted side effects, so it is important to see your doctor regularly while taking these medications. If you have any concerns about the side effects of corticosteroids, you should discuss them with your doctor.
