Stabbing pain six months after radical treatment of perianal abscess may be caused by various factors such as the wound has not yet fully recovered, inflammation stimulation, stimulation of postoperative scar, etc. The specific situation needs professional doctor’s judgment and cannot be generalized. 1. The wound has not yet fully recovered: the wound may not be completely healed during the recovery period, therefore, tingling may occur half a year after the operation. 2. Inflammatory stimulation: it may be due to the wound being infected and not under control, which in turn may cause tingling six months after the operation. 3. Stimulation of postoperative scar: If there is no infection in the anus, it means that the wound has completely healed. Therefore, the stinging pain six months after the operation may be a symptom of the stimulation of the postoperative scar. You can do proper anal lifting exercise to promote the softening of the scar and the recovery of the anal sphincter. If the stinging pain occurs six months after the radical treatment of perianal abscess, it may also be other reasons, you should go to the hospital in time to consult the doctor, clarify the cause of the disease, standardize the treatment under the guidance of a professional doctor, and follow the doctor’s instructions.
