Chest pain or Discomfort -The usual site of pain or discomfort is the central part of the chest. But it may also be felt (radiation) in the left shoulder, left arm and even in the hands. Uncommonly, the pain may radiate to the lower jaw, neck or upper part of abdomen (epigastrium). The discomfort could be expressed as a sense of heaviness or tightness in the chest or as a squeezing, choking or burning sensation (therefore, sometimes confused with heart burn).
