I had a hemmroids surgery 25 days back. Doctor done stapler surgery and also removed outer prolapsed hemmroids doing open surgery. After this surgery i have a constant issue of feeling a motion every time. Which is not reducing with  the time. I am still on pain killers voveran sr 75 mg. When i'm taking a pain killer then this feeling goes away. But when i try to leave voveran same feeling starts again. This is very uncomfortable feeling which keeps your mind involved with the feelig of passing a stool. What could be the reason.
