Pain in the arm can result from a number of factors. Abnormalities of the skin, nerves, bones, joints, blood vessels, and soft tissues of the arm can all result in pain. Sometimes diseases that affect other organs in the body, like peripheral vascular disease or arthritis, can be the cause of pain in the arm. Causes of arm pain range from mild annoyances to severe and potentially life-threatening occurrences, such as the pain from myocardial infarction and angina (chest pain) that may radiate (spread) to the arm area. Treatments for arm pain depend on the underlying cause
