[ ] Hi, it seems you have developed fissure in ano. ( a cut in anal canal due to passage of hard stool). You need some good laxative to make stool soft do that it should not hurt the wounded area. Take isabgol husk in Luke warm water after dinner daily. You can try Triphala powder. There are certain ointment to relax the anal sphincter which helps in relieving pain and allows fissure to heal. Do sitz bath three times a day. Feel free to ask any further quary.

Most likely cause is fissure in ano. But other causes are possible and have to be ruled out before treatment.

Please don’t start any treatment without a proper &complete diagnosis

This could be due to a small fissure in another, that is a crack in the anal edge skin, usually comes after passing a hard motion. Stool softeners,high roughage diet, regular bowel habit,local soothing creams will help. Good luck.
