Fibromyalgia and myofascial pain syndrome are the most common causes of chronic musculoskeletal pain in the practice of a neurologist. Fibromyalgia is a syndrome characterized by chronic musculoskeletal pain and the presence of palpable dolorogenic zones, defined as discrete areas of soft tissue, painful when pressed with little effort, indistinguishable from surrounding healthy tissue. At the same time, myofascial pain syndrome is associated with impaired motor and sensory functions and is characterized by the presence of myofascial trigger zones – hyperirritable nodes in skeletal muscle fibers. Currently, the differential diagnosis of these conditions is difficult due to the lack of clear criteria for diagnosis, and, therefore, these diseases are not correctly diagnosed too often. The wrong diagnosis of any of the conditions leads to a number of negative consequences, including unnecessary analyzes and examinations by various specialists, lack of improvement of symptoms, lengthening the time to establish the correct diagnosis, frustration of patients and increasing burden on the health care system as a whole. The article presents modern data on the pathophysiology, criteria for diagnosis and differential diagnosis of these conditions.
