Fibromyalgia (FM or FMS) is a debilitating chronic syndrome (constellation of signs and symptoms) characterized by diffuse or specific muscle, joint, or bone pain, fatigue, and a wide range of other symptoms. It is not contagious, and recent studies suggest that people with fibromyalgia may be genetically predisposed. It affects more females than males, with a ratio of 9:1 by ACR (American College of Rheumatology) criteria. Fibromyalgia is seen in 3% to 6% of the general population, and is most commonly diagnosed in individuals between the ages of 20 and 50. The nature of fibromyalgia is not well understood, with many frustrated physicians driven to accusing their patients of feigning illness.
