Abstract

Fibromyalgia (FM) is characterized by chronic widespread pain lasting for a minimum of three months and pain at mechanical pressure in at least 11 of the 18 tender points. Four treatment groups with FM patients and a healthy control group were followed within 3 months in the Clinic of rheumatology, Sofia. Fatigue in FM was assessed using the Chronic Fatigue Scale (FSS) and the Modified Fatigue Scale (MFIS). The results obtained have practical significance and provide the conviction to investigate the accompanying symptoms in FM, to consider the relationship between them and to observe their complex response to the treatment.
