Fibromyalgia is a common but contested illness. Its definition and content have changed repeatedly in the 110 years of its existence. ⋯ Fibromyalgia is closely allied with and often indistinguishable from neurasthenia, a disorder of the late 19th and early 20th centuries that lost favour when it was perceived as being a psychological illness. Fibromyalgia's status as a 'real disease', rather than a psychocultural illness, is buttressed by social forces that include support from official criteria, patient and professional organizations, pharmaceutical companies, disability access, and the legal and academic communities.
