Fibromyalgia is a common condition characterized by diffuse musculoskeletal pain and fatigue. The syndrome is defined by the presence of musculoskeletal tender points on physical examination. ⋯ Recent research has revealed a number of objective biochemical, hormonal and neurotransmitter abnormalities associated with fibromyalgia, making it a clearly identifiable condition. These abnormalities may clarify our understanding of the pathogenesis and treatment of fibromyalgia.
