Is it possible to be completely anaesthetised for a colonoscopy? I may have to have one as I have had severe constipation and the doctor is suspecting fecal impaction. I had one a year ago ( I have had 2 previously) and it was absolute agony - I screamed !! I have IBS and diverticulitis and assume this is why it is so difficult for them to perfection the procedure. I am now terrified of ever having it done again
