Very helpful responses. I think I am beginning to get a much better sense of what to expect during and after the procedure. When you say that towards the end the numbing was wearing off, I was wondering what kind of pain or sensation you felt. Obviously it must have been tolerable or else you would have asked for more anesthesia is that right? If I experience the same as you did, would you suggest I alert the doctor right away or just put up with it as long as it is tolerable?
