Fibromyalgia is a poorly understood complex, chronic disorder. It can cause widespread pain and stiffness, poor sleep and fatigue. It is often associated with other conditions including depression, anxiety, headaches, swelling of extremities, irritable bowel syndrome, and restless leg syndrome among others. It typically was a waxing & waning pattern that can be affected by weather changes, stress, overexertion, illness or surgery. The goal of treatment is to reduce symptoms and improve function, as there is no known cure. While treatment regimens vary widely, physical activity is of utmost importance.
