Although the cause of fibromyalgia remains unknown, researchers have isolated several factors which may increase a person's chances of getting fibromyalgia. For example, people who have relatives with fibromyalgia are more likely to develop the disorders themselves, leading researchers to believe that certain people are genetically predisposed to get fibromyalgia. This theory is further bolstered by common brain abnormalities found in patients who are diagnosed with fibromyalgia. Other contributing factors for this disorder do not appear to be genetic. Childhood stress and prolonged, day-to-day trauma are also viewed as contributing factors of fibromyalgia.
Some members of the medical community are reluctant to call fibromyalgia an actual disease. That's because the disease doesn't have any known causes, and it doesn't have any specific symptoms other than soreness, fatigue and pain -- symptoms shared by numerous other health conditions, including simple stress or depression. There are no diagnostic tests for fibromyalgia
Research is ongoing to improve the treatments available to fibromyalgia patients, as well as to learn more about the condition.
