I just had hemorrhoidectomy with longo method 8 days ago. There is currently no pain at the surgical site. But since the surgery is complete, I always have a dull stomachache and have a bowel movement 1-3 times a day. The doctor advised me to have abdominal pain and blood in my stool after cutting hemorrhoids with the longo method

I cut 4th degree mixed hemorrhoids with electric knife. After a few days, I had a very painful bowel movement and there was blood in the stool. When not defecating, there is mucus and blood seeping into the tampon. So the doctor asked me if pain with anal bleeding after hemorrhoidectomy is okay? Is my incision infected? Thank you doctor.
