Fibromyalgia is a disorder characterized by widespread musculoskeletal pain that has no apparent physical cause. The pain is often at its worst in the morning, most commonly affecting the lower back, neck, shoulders, the back of the head, upper chest, and thighs. The most distinctive aspect of fibromyalgia is tender points, specific spots on the body where the muscles are abnormally tender. Other common symptoms include fatigue, memory loss, mood issues like depression, chemical sensitivities and a compromised immune system. Although the cause of fibromyalgia is unknown, a hypoallergenic, anti-inflammatory diet is the best course of action for supporting the condition and reducing side effects.
