Wow what a story...I am so sorry it was that experience. Although I am NOT trained in medicine...I find it very unusual to schedule a colonoscopy without a GI consult first.

Generally they are done once we hit 50 and after we see a Gastroenterologist. I hope you call your primary for a little peace of mind. The urgent care doctor sounds like a real jerk.
Good luck, keep us posted.
