The primary symptom of FM is chronic widespread pain lasting more than three months and occurring in 11 of 18 specific tender-point sites. These symptoms vary and flare up with an increase in exercise, injuries, illnesses and psychological stress.
Exhaustion occurs from physical and mental effort.
Causes of fatigue include nonrestorative sleep, depression and hormone dysfunction. People with FM report feeling exhausted even after 8 to 10 hours of sleep. Often no cause can be found. Most FM patients claim their symptoms began after an injury or repetitive work-related pain. Studies have suggested that FM may develop as a result of a genetic pre-disposition waiting for a trigger.
