The most common symptom is chronic pain, which can be localized or involve several muscle groups. The common areas of pain include the neck, middle and lower back, chest wall, arms, and legs. The intensity of the pain is variable and can increase with several triggering factors. These factors include stress, lack of sleep, exertion, surgery, and changes in the weather.
Other factors associated with fibromyalgia include fatigue and sleep disturbances such as reduction in delta sleep and nocturnal myoclonus. Fatigue has been seen in about 90% of cases studied. Cognitive deficits in memory and vocabulary are also seen in patients with fibromyalgia.
