Fibromyalgia is a persistent illness that causes pain and discomfort throughout the body. The discomfort may be connected to fatigue, sleep issues, difficulty focusing, headaches, depression and anxiety. Tenderness in the joints, muscles, tendons and other soft tissues is another symptom of fibromyalgia.
People with this condition may have faulty pain perception processing, which makes them more sensitive to pain than those who do not have it.
In the United States, fibromyalgia affects roughly 4 million people. Women are far more likely than men to experience it.
