The most common cause of pressure pain on both sides of the chest is thoracic costochondritis. The thoracic cartilage is the cartilage inside the joint between the sternum and the rib cage, and aseptic inflammation in this area can cause pressure pain, and in addition to pressure pain, local pain can occur if the thorax moves, such as deep breathing, coughing, or when the upper limbs lift something with force, and when the chest has to hold its breath. If there is acute inflammation, there will also be local symptoms of redness, swelling, heat and pain, such as flushing of the skin and increase in skin temperature, etc. If there is chest tightness, palpitations or chest pain, and if the pain is compressive, it is necessary to pay attention to whether there is a heart disease, commonly acute myocardial infarction or angina. If the above symptoms occur, it is necessary to go to the hospital for an electrocardiogram and blood sampling to check the blood troponin for a clear diagnosis.
