Not really a diagnosis. The term refers to a symptom complex. Point is the term should be used once other causes of aches, pains, and cramps have bee excluded. The differential is immense and can include a variety of metabolic myopathies like myoadenylate deaminase deficiency to a disorder like polymyositis- inflammatory myopathy. Myopathy=muscle disease.
Everyone should be worked up using the term fibromyalgia in an exclusionary way.
