Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep and mood issues. Researchers believe that fibromyalgia amplifies painful sensations by affecting the way your brain processes pain signals.
Fibromyalgia is commonly thought of as a condition that affects adults. However, fibromyalgia also occurs in children and adolescents. Estimates suggest that juvenile-onset fibromyalgia affects 2 to 6 percent of school children, mostly adolescent girls. It is most commonly diagnosed between ages 13 and 15.
