colonoscopy was significantly more painful than my first one. appears I was given the same amount of sedation. Dr Kirby said it was due to the twists in my colon. assuming colons don't change in 6 years I can only assume this excessive pain was due to provider's technique. He was otherwise friendly and professional.
