Pain in the pectoral muscle may be caused by a pulling injury or a direct impact injury, or it may be caused by a local muscle or rib lesion. The doctor will make a preliminary analysis with the physical examination and, if necessary, improve the local CT to understand whether there are obvious lesions. If the pain is only caused by general trauma, first of all, the local area can be coated with some painkilling drugs such as etofenacin gel, if not allergic to creams, but also with painkilling creams such as flurbiprofen babu cream treatment. Local injury 24 hours later can be combined with hot compresses, appropriate rest, avoid lifting heavy objects on the upper extremities to help relieve pain.
