Pain in the chest after a cold may be caused by the following reasons: 1. It is possible that the soft tissues or articular cartilage in the chest have become poorly circulated and the blood vessels have contracted due to the cold, thus causing ischemic pain. The symptoms will be relieved after local hot compresses and warm clothes are applied. 2. It may be a heart problem, if the heart is stimulated by the cold, patients with a history of hypertension, diabetes, coronary heart disease, etc. are most likely to have an acute heart attack. Usually in addition to local wound pain will be accompanied by chest tightness, palpitations or some patients will also appear to have dizziness, cold sweats, weakness of the limbs and other conditions. If this occurs, the most common cause is angina pectoris or acute myocardial infarction, and the patient should immediately go to the hospital for relevant examination and treatment.
