hi all,i have had all the tests done apart from a colonoscopy, the last time i saw my doctor was about a year ago and he said the only thing left to do was have a colonoscopy. i am now (once again) getting sick of this ibs and are thinking of going and getting it done.i was wondering if is worth doing as i know i have ibs and i don't see the point of going through all that discomfort for them to tell me that i have ibs.Is it likly they might find something that they can cure? i arnt too fimilar with what the are exactly looking for, so any help on this matter would be much appreciated.thanks all
