If there is pus inside the wound after scabbing, it may be caused by wound infection or a foreign body inside the wound. In this case, you need to go to the hospital for general surgery and emergency surgery, flush the wound with saline and hydrogen peroxide, disinfect the wound, and if there is pus or foreign body, cut and drain the wound together to remove the foreign body. Pus in the deeper layers of the wound will affect the wound healing and will lead to pseudo-healing of the wound surface, so it is necessary to drain the wound promptly. If necessary, apply antibacterial drugs, including cephalosporins and anti-anaerobic drugs, for symptomatic treatment. Also pay attention to rest, less activity, and a light diet with less spicy and stimulating foods. Change the medication every two days or so to observe the condition of wound changes.
