Fibromyalgia is a chronic, extensive muscle pain that has no obvious cause. Pain is usually described as pain, stiffness, or burning and can occur anywhere on the body, but for the diagnosis of fibromyalgia, there must be pain in at least 11 of the 18 specific "sensitive points". The pain from the sensitive points but also from other parts of the body is usually more intense after waking up and gradually decreases as the day progresses. The sensitive points in fibromyalgia are present in pairs, one on the right side of the body and one on the left. Many studies show that fibromyalgia is a systemic biochemical disorder that is affected by many imbalances throughout the body.
