Fibromyalgia is a syndrome with heterogeneous symptoms. The importance of each symptom has not been fully established, though widespread body aches, pain, tenderness, fatigue, and sleep disturbances are common symptoms.(1) The evaluation in the clinical setting usually fails to cover the complexity of the syndrome, and clinicians do not utilize available clinical tools—such as questionnaires to evaluate pain, fatigue, and quality of life—to improve understanding of individual cases and guide management of each patient’s symptomatology.(2) 1.
