To be honest with you, Capricorn, a colonoscopy is the FIRST thing I had done. It may not be necessary nor the Rome criteria require it, but it certainly gave me peace of mind. Along with having the peace of mind to know I did not have cancer, I also found out I did not have colitis, diverticulitis, etc. So, for me it was well worth it. I personally think it should be done, regardless if it is required or deemed necessary. But that is IMHO.
