Fibromyalgia is a common rheumatic syndrome that affects approximately 3% of the population, mostly women.
It indicates widespread pain in fibrous tissues, muscles, tendons and other connective tissues, causing muscle pain without weakness. The cause of this disorder is unknown, although it is a chronic problem that may come and go for years.
Among other symptoms, causes muscle pain, fatigue, depression and insomnia. Diagnose can take two to three years, even more, because so far the only way is to discard all rheumatological and neurological diseases with similar symptoms.
