Characterizing fibromyalgia flares: a prospective observational study.

Introduction: Although most patients with fibromyalgia describe periods of exacerbation of their symptomatology, there are very few studies describing its characteristics.

Material And Methods: We recruited a total of 124 patients from our outpatient clinics who agreed to a follow-up of at least 6 months. All of them were asked to note and describe whether they had had any worsening of their symptoms during that time.
