Fibromyalgia is a debilitating constellation of signs and symptoms characterized by diffuse 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. Fibromyalgia is seen in 3-10% of the general population, and is mostly found between the ages 20 and 50. The nature of fibromyalgia is not well understood, and there is no cure, though it can be managed.
