Characterized by chronic, widespread pain and heightened pain sensitivity, fibromyalgia affects up to 10 million adults. It is physically disabling and often is accompanied by chronic fatigue and psychiatric comorbidities. Individuals frequently see multiple providers before finding an answer about their condition; diagnosis is often a process of elimination. Etiology is unknown, but studies suggest fibromyalgia is a centrally mediated neurosensory disorder. Despite its recognition as an independent condition, debate continues with critics arguing fibromyalgia is a variant of other known disorders. Treatment consists of pharmacotherapy, psychotherapy, and exercise.
