Fibromyalgia
People with this condition will suffer widespread chronic pain, fatigue, memory problems, and mood changes. The persistent pain and fatigue can lead to depression and anxiety for some patients, says Dr. Goitz. Researchers suspect that many medical issues—alone or together—may contribute to the development of fibromyalgia.
Research has linked the disease to stress; it also appears to run in families. The mainstay of treatment is sleep and physical activity, and some people may find medications help them manage the condition.
