Fibromyalgia is a chronic condition that causes widespread musculoskeletal pain and other symptoms such as stiffness and achiness, tender points (or trigger points), fatigue, and cognitive or sleep issues. It affects up to 6.4 percent of U.S. adults and more women than men.
Considered a pain disorder, fibromyalgia is strongly associated with rheumatic diseases and can be confused with arthritis because it causes pain in joints, soft tissues, and muscles. Because symptoms can mimic other conditions, it can lead to a misdiagnosis.
