Yes, public hospitals can do it, but the best is your local Chinese medicine hospital. Chinese medicine is better at anal diseases than western medicine. If anal fissure occurs, you can use an airtight air cushion to hang the anus and sit and breathe, so that the wound will be much more comfortable. Wash with a hand-held towel after defecation, and the wound must be clean. The most important thing is to do potassium permanganate fumigation and sitz bath with anal hydrotherapy instrument to ensure enough time. You can prepare an anorectal rehabilitation package, or be careful of fakes. The fake painless breathable pad has a very small overhead area and does not have the effect of overhead wound. Go to the hospital as soon as possible. Good luck.
