Patients with perianal abscesses have itchy wounds after surgery, which is a normal reaction and is considered to be caused by inflammation stimulating the proliferation of local scar tissue. In addition, we should also pay attention to the diet regulation. During the treatment period, patients with perianal abscess should stay away from spicy food and stimulating food, and stay away from the environment of smoking and alcohol, because these bad dietary and living habits will lead to local vasodilation of the wound and aggravate the scar formation, so it will also lead to the aggravation of itching and pain symptoms. In addition, pay special attention to the hygiene of the perianal area, and in the acute stage with obvious inflammatory reaction, anti-infection treatment should be continued.
