The objective of this article is to review some aspects of the fibromyalgia syndrome and its mechanisms of development. We also discuss how to go from preclinical research to clinical practice. Fibromyalgia is a clinical syndrome whose main features include diffuse musculoskeletal pain, fatigue, sleep disturbances, and cognitive disorders. Russell & Larsson (2009) proposed "pronociceptive" and "antinociceptive" systems under normal conditions. Functional pain states such as fibromyalgia are derived from central disturbances in pain processing. The association with anxiety and depression is a negative prognostic factor. Distress is an important part of its physiopathology. The concomitance of other functional syndromes is a rule. The already known etiopathogenic mechanisms of fibromyalgia can be applied in clinical practice for diagnosis and rational therapeutic approaches. Pharmacological but mainly nonpharmacological measures must be applied. Although much information still needs to be obtained, the clinician presently has sufficient tools for efficiently treating fibromyalgia patients. An important aspect is that such knowledge needs to reach primary care physicians because the prevalence of fibromyalgia does not allow all patients to be treated by specialists.
