Try not to wipe the anus with alcohol, because the anal skin mucosa is fragile and thin, so if you wipe the anus with alcohol, it will cause local skin mucosa congestion and pain, especially when accompanied by perianal diseases, including perianal abscess and rectoanal canalitis, etc. If you repeatedly stimulate with alcohol, it will easily lead to congestion, swelling, and even severe pain. When disinfecting or examining the anus, you can apply iodophor or iodine to wipe the anus locally, which can not only disinfect and sterilize the anus, but also reduce the stimulation of the local anus by the liquid, and at the same time, you should regularly go to the clinic for anoscopic rectal examination to detect the lesion early and give the corresponding symptomatic treatment measures in time.
