Polymyalgia rheumatica is a rare inflammatory disease characterized by muscle pain (myalgia), stiffness, and additional generalized systemic symptoms such as fatigue, low-grade fever, and/or a general feeling of ill health (malaise). Polymyalgia rheumatica can be a relatively benign condition that is extremely responsive to treatment. In some rare cases, permanent muscle weakness, degeneration and loss (atrophy) of muscle mass, and disability may occur. The exact cause of polymyalgia rheumatica is unknown, although immunological factors and familial tendencies (genetic predisposition) have been mentioned in the medical literature.
Polymyalgia rheumatica is closely related to giant cell arteritis, another inflammatory disorder. Giant cell arteritis is characterized by progressive inflammation of many arteries of the body. These two disorders have been described in the medical literature as possible variants of the same disease process. Some researchers believe they represent different ends of a disease continuum. The exact nature of the association is not fully understood.
