There are very many reasons for pain under the heart. The first one, if it is related to activity, may be a heart problem, especially coronary artery disease and angina attack. If the pain occurs after regular activity and then can be relieved soon, usually after 3-5 minutes of rest, consider having coronary heart disease. The second type of pain is related to eating, such as pain under the heart after hunger or a full meal, which is initially considered to have gastritis or even gastric ulcer or duodenal ulcer. The third type of pain may be the pain in the chest wall, such as local inflammation or inflammatory diseases that cause pain under the heart. But inflammatory diseases, which are not regular, may be painful in general, and the pain may be more pronounced when pressed. The fourth, to rule out the presence of shingles, shingles is a viral infection that causes pain that can be more intense. The fifth, costochondritis, is more pronounced when pressure is applied. Therefore, the cause of pain under the heart should be found and gradually ruled out.
