Polymyalgia rheumatica is a rheumatic disorder associated with moderate-to-severe musculoskeletal pain and stiffness in the neck, shoulder, and hip area. Stiffness is most noticeable in the morning or after a period of inactivity, and typically lasts longer than 30 minutes. This disorder may develop rapidly; in some people it comes on literally overnight. But for most people, polymyalgia rheumatica develops more gradually.
The cause of polymyalgia rheumatica is not known. But it is associated with immune system problems, genetic factors, and an event, such as an infection, that triggers symptoms. The fact that polymyalgia rheumatica is rare in people under the age of 50 and becomes more common as age increases, suggests that it may be linked to the aging process.
Polymyalgia rheumatica usually resolves within 1 to several years. The symptoms of polymyalgia rheumatica are quickly controlled by treatment with corticosteroids, but symptoms return if treatment is stopped too early. Corticosteroid treatment does not appear to influence the length of the disease.
