The anorectal department of Chinese medicine hospital is generally strong. In addition, I suggest that you prepare an anorectal rehabilitation bag, which contains a hand-held washcoat to help you clean after defecation (this can ensure that you clean after defecation, and you can only wipe the stool into the wound with paper), and an anal hydrotherapy instrument to help you fumigate with warm water, preferably potassium permanganate. Pay attention when buying, many seemingly cheap ones are used for disinfection of fish tanks and animals, so don't buy them wrong. Painless breathable pad can help to pause the wound and promote edema regression (students, drivers and office workers should pay special attention). The hospital has an anorectal rehabilitation package, but it is more expensive. It is recommended to buy on a treasure, but pay attention to identification when buying, and be careful to buy fakes that look cheap. If you feel serious, see a doctor as soon as possible. I wish you a speedy recovery.
