title: [Fibromyalgia and its diagnosis].
abstract: Fibromyalgia or fibromyalgic syndrome (FMS) is a clinical picture of unknown origin that is characterized by generalized, incapacitating and chronic pain together with the demonstration in the physical examination of previously defined points in which moderate pressure causes pain, called fibromyalgia tender points (FTP). FMS lacks objective, analytic imaging or pathological data, so that its diagnosis is based exclusively on subjective data, such as that the pain reported by the patient and the pain caused by the FTP pressure. Although the fibromyalgia classification criteria of the American College of Rheumatology are not diagnostic criteria, they have been extensively used to diagnose FMS in patients with chronic diffuse arthromyalgias. Fibromyalgia diagnosis reduces the patient's anxiety, avoiding complementary expensive and unnecessary tests and it allows the patient to share his/her fears, illnesses and expectations with other human beings who suffer the same problem.
