Like all who have sent you best wishes, let me add mine.. I am a nurse, and I have seen many colonoscopies--the patients have seemed comfortable and not in the "excessive pain" category your stupid MD described...the prep however is not fun ( I can't keep the stuff down, so I have not had one yet), but if you can do that part, you should not have a real problem with the test..a girlfriend of mine just had one and she did not complain about the test--just the prep--so take heart and give yourself a hug--we are with you!!!
