Patients who have been inadvertently pinched with local bruising can take different treatment methods according to the extent of local bruising and the degree of injury. If the patient’s local injury is mild and the extent of bruising is small, local blood circulation can be improved by applying local blood-stasis ointment and taking oral medications such as maziling and swelling pain to promote faster absorption of the bruising, which will not cause serious infection. Second, if the patient’s local injury is more serious and the scope of bruising is larger, the patient will often combine obvious swelling and pain, and the bruising cannot be removed faster simply by external application and oral medication. If necessary, patients need to perform surgical incision of the skin and subcutaneous tissue to remove the bruises, thorough disinfection of the wound, hemostatic treatment, and local pressure bandaging after surgery, which can effectively avoid the occurrence of local infection.
