The most frequent accompanying symptoms are: fatigue, sleeping disorders, chronic migraine, irritable bowels syndrome and others disorders. There is an important emotional influence related to stress response. Education, social and economical status could influence clinical presentation.

Family income was evaluated according to the number of minimum wages earned monthly and education according to complete years of formal education. Comparison among groups was analyzed using Chi-square, ANOVA tests and difference among average values. RESULTS: Studied groups were similar regarding to pain, fatigue, anxiety and depression intensity, and number of painful spots, regular practice of physical exercises and disease duration.
