The most common cause of chest pain from overexertion is a strain on the intercostal muscles or fascia. The thorax has to be contracted or stretched when a person exerts force, and if the explosive force at that time is large, it is likely to cause strain on the intercostal muscles and fascia. Usually in this case, there are very obvious local pressure points. The pain will appear during deep breathing or coughing, or will worsen on top of the original pain. Other activities of the thorax, such as turning around or the moment of lying down and getting up, can also cause pain in the injured area; it may also occur in patients who usually have hypertension, diabetes, or coronary heart disease. If there are these underlying diseases, it is possible that a heart attack, such as an attack of angina pectoris or myocardial infarction, may be induced after exertion. Usually, in addition to localized chest pain, it is accompanied by palpitations, chest tightness, dizziness, and weakness of the limbs. If the above symptoms occur, the possibility of acute heart disease is highly suspected, and you should immediately go to the hospital for an electrocardiogram and blood troponin tests to confirm the diagnosis.
