Burning pain after anal fissure surgery



I recently had surgery to repair an anal fissure. About 3 days after surgery, I began having an extremely severe burning pain every time I have a bowel movement. (It feels like someone is pouring acid on me.) I am on pain medication and 2 types of stool softeners. After the bowel movement, I immediately use warm water and peri wipes to cleanse the area, and I also sit in a sitz bath for 15-20 minutes, however, it still takes about a 1/2 hour for the burning pain to subside. Is this normal? Thank you.


This is normal. You have a healing wound. If you experience swelling or increasing pain, call your doctor's office.
