Conditions that cause aches and pains throughout the body include fibromyalgia, flu, lyme disease, hypothyroidism and chronic fatigue syndrome, according to Mayo Clinic. Injury, stress, tension and overuse of muscles may cause localized aches and pain.
Fibromyalgia causes widespread pain and aching throughout the musculoskeletal system, states Mayo Clinic. The term widespread indicates that the pain occurs both above and below the waist and on both sides of the body. Aching caused by fibromyalgia typically lasts at least three months. The condition can be brought on by physical trauma or surgery, and in some cases there is no clear cause or trigger.
Symptoms of fibromyalgia include fatigue, mood swings, tension headaches and sleep memory, according to Mayo Clinic. In many patients, fibromyalgia may be the result of an abnormal sensitivity of neurotransmitters in the brain, causing them to overreact to signals of pain. Other symptoms include irritable bowel syndrome, abdominal cramping, depression, anxiety and joint pain. Additionally, patients may experience an inability to focus or concentrate and other cognitive difficulties may be impaired.
Women are more prone than men to developing fibromyalgia, states Mayo Clinic. People with rheumatic diseases, such as rheumatoid arthritis or lupus, are also at higher risk.
