That same thing happened to my Mother on her last colonoscopy. She'd had many before and was out cold for them. She said it was horrible and she could feel every bend and twist they made. They knew she was awake but said they had given her as much of the "twighlight" sleep medication that they could give her so she suffered in agony through the whole procedure. That was the first time I'd ever heard of anyone being awake for the procedure. Needless to say, I'm in no hurry to schedule my next one
Sorry you had to go through that. I hope they find something that helps with your problems.
