Polymyalgia rheumatica (PMR) is an inflammatory disorder. It involves pain and stiffness in the shoulders and often the hips.
Polymyalgia rheumatica most often occurs in people over 50 years old. The cause is unknown.
PMR may occur before or with giant cell arteritis (GCA; also called temporal arteritis). This is a condition in which blood vessels that supply blood to the head and eye become inflamed.
PMR can sometimes be hard to tell apart from rheumatoid arthritis (RA) in an older person. This occurs when tests for rheumatoid factor and anti-CCP antibody are negative.
The most common symptom is pain and stiffness in both shoulders and the neck. The pain and stiffness are worse in the morning. This pain most often progresses to the hips.
Fatigue is also present. People with this condition find it increasingly hard to get out of bed and to move around.
Other symptoms include:
Without treatment, PMR does not get better. However, low doses of corticosteroids (such as prednisone, 10 to 20 mg per day) can ease symptoms, often within a day or two.
Corticosteroids can cause many side effects such as weight gain, development of diabetes or osteoporosis. You need to be watched closely if you are taking these medicines. If you are at risk for osteoporosis, your health care provider may recommend you take medicines to prevent this condition.
For most people, PMR goes away with treatment after 1 to 2 years. You might be able to stop taking medicines after this point, but check with your provider first.
For some people, symptoms return after they stop taking corticosteroids. In these cases, another medicine such as methotrexate or tocilizumab may be needed.
Giant cell arteritis may also be present or can develop later. If this is the case, the temporal artery would need to be evaluated.
More severe symptoms can make it harder for you to work or take care of yourself at home.
Call your provider if you have weakness or stiffness in your shoulder and neck that does not go away. Also contact your provider if you have new symptoms such as fever, headache, and pain with chewing or loss of vision. These symptoms may be from giant cell arteritis.
There is no known prevention.
