I voted colonoscopy/ endoscope. But I think the worst test I have had to have was when I was first getting diagnosed. I was 12( maybe 13) years old and my mom came and told me they had to run one more test before I could be discharged from the hospital. It was called a barium enema. It was horrible. I was crying the whole time. It hurt, and they wanted me to get into all kinds of positions all the while having the thing that felt HUGE stuck in my butt pumping the barium in. It was the longest test ever. I hope I never have to go through that again! Colonoscopes are scary, I hate the prep( don't know anyone who would like it!) but since I'm sedated for the scopes and EGDs, the prep is defiantly the hardest part.
Yea rectal exams are not a walk in the park either. Its not just the discomfort and pain at times, I'm so embarrassed and self conscious during the whole exam. uGh
