Fibromyalgia is a kind of medical condition that causes widespread, persistent pain. Symptoms of fibromyalgia include intense tiredness, difficulty sleeping, and muscle pain.
The word fibromyalgia is built from Greek and Latin roots: The Latin root fibro- means "fiber" (as in the fibers of one's muscles); the Greek root myo- means "muscle," and the Greek root -algia means "pain." Medical professionals are not sure what causes fibromyalgia, and there is no definitive test to diagnose the condition or a cure for it. It is believed to be a nervous system disorder that affects how pain signals are processed. Treatment focuses on managing the symptoms.
