This is a poorly defined syndrome which is commoner in females than in males and usually develops in young adults. Its characteristic features are fatigue with tenderness over various points, particularly in the chest and abdomen, and diffuse musculoskeletal pain and stiffness. This is usually worst around the neck and shoulders on waking, whereas in normal subjects the pain threshold is highest on waking.
Sleep is usually felt to be light and unrefreshing and this correlates with the number of tender points. Tiredness is common during the day, but it is unusual for sleep to be entered. Fibromyalgia may have a similar pathogenesis to the chronic fatigue syndrome, with hyperarousal, changes in endocrine function and in autonomic responses, abnormal reactions to stress, and a particularly increased sensitivity to pain.
