That's too bad. I had a colonoscopy and it was a piece of cake, no pain, nothing. Seemed like it was over before it began. Maybe he's having a reaction to the sedative, unless they found something and removed it from his colon, which might've created some pain. (Maybe all that spaghetti (not "pasta")). The worst thing about the whole experience for me was the preparation - you have to take this disgusting laxative for a day or two before the procedure to clear the colon. THAT was AWFUL.
I believe he said he had polyps removed.
gotta lay off the hot peppers for awhile!
