La fibromyalgie : diagnostic positif, diagnostics différentiels et diagnostics associés

Fibromyalgia is a frequent pain condition. The main symptom is chronic widespread pain during at least 3 months. Many other comorbidities and symptoms are also present. Diagnosis has been revised at multiple occasions during the past 2 decades. The concept is still discussed considering FM as a unique diagnosis or a condition including multiple illnesses. The recent revision in 2016 provides an update to the criteria in order to avoid misclassification (depression). Indeed, applying the previous criteria to regional pain syndromes led to over diagnosis. However, the criteria are non sufficient to diagnose FM; complete medical history and physical examination are necessary. There are also diagnostic confounders which should be identified. Moreover, some of these confounders may also be associated in some cases with FM.
