Fart when the anus hurts. What's going on here?

I can basically confirm that yours is an early anal fissure. As long as the anus is open, it won't hurt. Farting is very effective. Take good care of it. If it's serious, you have to go to surgery. It hurts! I have had hemorrhoid+anal fissure surgery for 50 days. I'll give you some advice. After defecation every day, 1 take a sitz bath with 50-degree water for 20 minutes to clean the anus. 2 you must defecate once a day, and try to defecate as early as possible; According to the current condition, eat more vegetables and fruits every day, eat less staple food, eat less greasy, spicy and seafood, and eat whatever is convenient; 4 It is very difficult to lift the anus 100 times a day. Inhale slowly, inhale and contract the anus at the same time, hold for 3 seconds, and exhale slowly, counting once.

You are early, I hope you take good care of yourself, don't go for surgery, it hurts to hit the wall!
