Trendsetter, I talked the hospital into doing it as a diagnostic rather than screening so it would be covered at age 45. So now they have checked everything in my gut except where I tell them it bothers me. Got an endoscopy same time. Hernia that I told them was there. Small they say. I am sure it was when I was dehydrated, sedated, prostrated, and empty boweled. Here in the real world I have a hell of a time swallowing. Seven years until doc plays with my butt, three for the endo.
