There are many causes of chest pain. One is angina which results from inadequate oxygen supply to the heart muscle. Angina can be caused by coronary artery disease or spasm of the coronary arteries. Chest pain can also be due to a heart attack (coronary occlusion) and other important diseases. Do not try to ignore chest pain and "work (or play) though it." Chest pain is a warning to seek medical attention.
