The main reasons for the recent chest pain include the following: the first reason is due to the cardiovascular system diseases of the body. Most of them are due to the history of exertional angina, myocardial ischemia and myocardial infarction, and the recent emotional excitement or work strain, which leads to chest pain. This kind of chest pain can be clarified by electrocardiogram and cardiac ultrasound. Treatment requires oxygen and rest, with symptomatic treatment such as taking drugs to improve the heart muscle. The second cause is due to respiratory diseases, including acute and chronic pleurisy, spontaneous pneumothorax, ruptured pulmonary blisters, etc., which can also cause chest pain. The chest pain caused by respiratory system diseases will be accompanied by coughing, wheezing and other respiratory symptoms. It can be clarified by performing chest X-ray examination. Thirdly, it is considered to be caused by the strain of chest muscles and soft tissues, which can be cured by taking blood-activating drugs.
