If the patient has pain in the right side of the chest, it may be due to the presence of intercostal nerve inflammation, as well as the presence of recent strenuous exercise, overexertion, resulting in joint muscle strain or strain, and in some cases, even the presence of pneumothorax, pleural effusion and other related diseases. If these diseases occur, the pleura or peripheral nerves may be stimulated, resulting in such pain symptoms. By combining the patient’s specific medical history and completing chest X-ray, chest CT and other related imaging examinations, the specific condition can be clarified. For example, if the patient is found to have a large amount of pneumothorax, the patient can be treated symptomatically by closed chest drainage surgery.
