Chest pain may be due to costochondritis, sternitis, soft tissue contusion or heart disease. 1. Costal chondritis: Costal chondritis may be aseptic inflammation, due to cartilage strain caused by maintaining a posture for a long period of time, such as long time in bed looking at the cell phone, typing in front of the computer, etc., which is mainly manifested as pain in the upper chest, and may be accompanied by localized redness and swelling of the skin. 2. Soft tissue contusion: soft tissue contusion in the upper chest area may lead to local pain, but usually there will be impact injury in the upper chest area or thoracic compression injury. 3. Heart disease: angina pectoris or acute myocardial infarction is common, which may be accompanied by palpitations (rapid heartbeat, often accompanied by panic), chest tightness and pallor and other symptoms. If you have chest pain, you should consult a doctor in time for diagnosis.
