Pph hemorrhoids surgery left a centimeter-long incision behind the anal orifice. What principle did the doctor say the operation left behind?

Hello: It's a scar left after the excision of the middle and external hemorrhoids in hemorrhoids surgery. I suggest that you smoke and wash around the anus with local hot water every day (use hot air in hot water instead of sitting bath, be careful not to burn it to the temperature) 15-20 minutes, and then dry it. Be sure to dry it and keep your skin dry. Promote the absorption of surgical scars, keep the stool smooth and not dry, and prohibit spicy, alcohol and seafood diets.
