I had an extremely painful colonoscopy, during which I was awake and alert. I screamed in pain during the procedure and the doctor couldn't complete it due to deep of "looping and redundancy"of my colon. Later, a lower GI indicated the possible presence of a tiny polyp. I need to have a complete colonoscopy now in order to see if a polyp exists. What can I do in order to minimize the pain? Also, I've since done a good deal of research on the drug Versad, and don't wish to have it used on me again as it didn't work.
