Painful symptoms occur when the chest is twisted, and the common reasons are mainly the following: a. After chest muscle exercise, no proper relaxation physical therapy will cause a large amount of lactic acid and metabolic waste deposited at the chest muscles, causing pain when the patient moves. The pain symptoms can be reduced by adequate rest, proper massage of chest muscles, physiotherapy, external application of hot amoxicillin pack, fumigation with moxibustion strips, and external application of blood circulation and stasis cream to promote faster absorption of local lactic acid and metabolic wastes. Second, inadvertent fall of ribs during physical exercise can cause rib fracture and cause pain in the chest, which can lead to breathing difficulties and restricted activities. It is necessary to improve the X-ray or CT examination of the chest as soon as possible to clarify the severity of the rib fracture, and if necessary, perform surgery for internal fixation to relieve the painful symptoms in the chest.
