Fibromyalgia is characterized by widespread musculoskeletal pain
accompanied by fatigue, sleep, memory, mood issues and a variety of other symptoms (see above). Researchers believe that fibromyalgia amplifies painful sensations by affecting the way your brain processes pain signals.
Symptoms sometimes begin after a physical trauma, surgery, infection, or significant psychological stress. In other cases, symptoms gradually accumulate over time with no single triggering event.
Women are more likely to develop fibromyalgia than are men. Many people who have fibromyalgia also have tension headaches, temporomandibular joint (TMJ) disorders, irritable bowel syndrome, anxiety and depression.
