AgreeI had a pretty bad abscess when I had my colonoscopy. The surgeon wasn't worried at all. They gave me some sort of drugs and I didn't feel anything. I don't know about the tear though. I'd call the docs office and let them know about it soon, so they can reschedule if need be.
Did your talk to your doctor Badtummy4? If they were already aware of the tear then I imagine that's why they wanted to do a scope to see if there was anything else going on. If they aren't aware of it then they need to know just in case. I haven't heard anyone mention that they weren't able to have a scope done because of a fissure or abscess. Keep us posted.
