After waking up, if there is pain in the chest, first of all, we must determine whether there is any relationship between this chest pain and the activities of the thorax, if it is the activities of the thorax, such as chest lifting, deep breathing or coughing hard, or pain in the chest when the upper limbs move something hard, it is usually a problem of the soft tissues of the thorax, such as the chest, due to long time pressure when sleeping or some rib chondritis near the thorax, or some aseptic inflammation such as thoracic costochondritis, sarcopenia, etc, These conditions can generally be caused by external application of some ointment to relieve swelling and pain, dispel wind and dampness, or eat some non-steroidal anti-inflammatory drugs, the symptoms can be slowly relieved. However, if there is no relationship with chest activity, and in addition to chest pain, it is accompanied by chest tightness, palpitations, dizziness, and weakness of the limbs, it may be an acute heart disease, commonly known as angina pectoris or myocardial infarction. This situation should immediately go to the hospital to improve the electrocardiogram, as well as blood troponin to confirm the diagnosis.
