The symptoms of fibromyalgia can vary from mild to severe and may go on for a long time and should be discussed with your health care professional. Fibromyalgia is not considered to be life-threatening, and its symptoms may not necessarily get worse with time. Although fibromyalgia cannot be cured, many people with fibromyalgia are able to manage their symptoms with proper treatment.
