<h3>Background</h3> Fibromyalgia is a common cause of chronic musculoskeletal pain in the world, with diverse clinical manifestations and with a ruinous effect on the quality of life of patients. The estimations of prevalence in the general population are very variable (0.2% - 6.4%) as well as the clinical presentation. <h3>Objectives</h3> This study aims to describe the sociodemographic and clinical characteristics of patients with fibromyalgia treated in a specialized institution between 2010 and 2016, in Medellín, Colombia. <h3>Methods</h3> We performed a retrospective, descriptive, secondary source study of patients diagnosed with fibromyalgia from a specialized institution between 2010 and 2016. Descriptive statistics and period prevalence tools were applied for the variables studied, among which was evaluated the use of the diagnostic criteria (1990 or 2010) of the American College of Rheumatology. <h3>Results</h3> We evaluated 1106 records of patients diagnosed with fibromyalgia. The median age was 54 years (IQR 16), the age of greatest presentation is between 40 and 65 years for both sexes, 95.1% were women and a 51.1% were married or living with their partner. 23.6% of the patients had a basic and middle level education (secondary and technological level), 93% of the population came from the department of Antioquia (for a prevalence for this institution in the period 2010 to 2016 of 0.017%), and 54% resided in the city of Medellín. The proportion of people with low and medium low socioeconomic status was 26.3%, while 41.4% reported being active in a job. The symptoms most frequently presented among the patients were myalgia (70.2%), sleep disturbances (59.9%), chronic fatigue (48.5%), headache (47.3%) and muscular weakness (40.5%). When analyzing by sex, headaches were more frequent in women (48.8%) than in men (24.1%). The most commonly reported comorbidities were psychiatric disorders (31.1%, where depression was the most recorded with 24.1%), migraine (30.9%) and hypertension (27.9%). The most used criteria to make the diagnosis of fibromyalgia were those of 1990 with 62.2%. Regarding treatment, the most used were serotonin reuptake inhibitors and dual inhibitors (52.6%), along with acetaminophen (41.2%) and pregabalin (39%); only 8.2% of patients received non-pharmacological interventions (physical and psychological therapy). <h3>Conclusion</h3> Fibromyalgia is an important pathology in specialized medical consultation, accompanied by myalgia, sleep disturbances, chronic fatigue, headaches and muscle weakness. Psychiatric pathologies are the most frequently associated comorbidities and the 2010 criteria of the American College of Rheumatology are not yet widely applied. The treatment of fibromyalgia is complex and probably more effective with a transdisciplinary approach involving both pharmacological and non-pharmacological interventions. <h3>References</h3> [1] Wolfe F, Walitt B, Perrot S, Rasker JJ, Häuser W.
