Fibromyalgia is a condition characterized by widespread pain throughout the body and affects 2-4% of the population, predominantly women. Common symptoms include fatigue, joint stiffness, muscle pain, and mood issues like depression and anxiety. While the cause is unknown, risk factors include heredity, injuries, infections, and psychological stress. Treatment options consist of medications like Lyrica, Cymbalta, and antidepressants as well as exercise, which can help reduce pain and fatigue while improving mood, though overexertion risks exacerbating symptoms.
