Fibromyalgia
Fibromyalgia (FM or FMS) is a 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, though onset can occur in childhood. The disease is not life-threatening, though the degree of symptoms may vary greatly from day to day with periods of flares (severe worsening of symptoms) or remission. The syndrome is generally perceived as non-progressive, yet that issue is still debated.
