Pain Neuroscience Education as Treatment in Fibromyalgia Affected Patients

Fibromyalgia (FM) is a chronic, complex and disabling clinical entity that has an average global prevalence of 2.7%. It occurs mainly in women in a 3: 1 ratio. It is characterized by persistent generalized pain, fatigue, unrefreshing sleep, cognitive dysfunction and numerous systemic symptoms such as dizziness, migraine, digestive alterations or sensory intolerances. At present there is no pharmacological treatment with specific indication for fibromyalgia. Usually, non-curative treatments are recommended that alleviate the symptoms of the patients and improve their quality of life and functionality. The investigator's main goal is to evaluate the effectiveness at 1 year of a group educational intervention in neurobiology of pain in patients affected by fibromyalgia, in comparison with the evolution of a control group that will continue only with its usual treatments. This intervention will be carried out in the field of Primary Care and its effectiveness will be assessed by reducing or not having diagnostic criteria (reduction of areas of pain and of the severity of fibromyalgia symptoms), using the Criteria for the Diagnosis of Fibromyalgia of the American College of Rheumatology 2010 (ACR 2010).
