Chest bone mainly has sternum and ribs, sternal pain may be caused by trauma, angina pectoris and myocardial infarction, osteophytes, costochondritis and so on. 1. Trauma: When the sternum is traumatized, such as when it is violently hit, it will lead to chest muscle as well as bone damage, which will cause pre-sternal bone pain. 2. Angina pectoris and myocardial infarction: atypical angina pectoris may be manifested as persistent pain or paroxysmal pain in the anterior chest area, which may be accompanied by palpitation and chest tightness, and electrocardiogram reveals obvious myocardial ischemia, and pain in the anterior chest area also occurs in the case of myocardial infarction. 3. Osteomalacia: the elderly may have osteophytes in the thoracic rib joints, which irritate the surrounding soft tissues and cause anterior chest bone pain. 4. Costochondritis: prolonged exposure to cold in the chest or prolonged physical labor, as well as viral and other infections, can cause inflammation of the sternum and rib cartilage, resulting in severe pain in the anterior sternum, which is aggravated by pressure. In addition to the above common causes, you should also be alert to aortic coarctation, pancreatitis radiating pain and other emergencies, and you should consult a doctor as soon as possible, under the guidance of a professional doctor for diagnosis and treatment.
