I am getting a colonoscopy on Tuesday, after about 6 months of worrying about colon cancer. I went to my GP for a physical, told him of my fears, and he suggested the colonoscopy to put my mind at rest. Frankly, I am not worried at all about what you are - unclean instruments, etc., but am totally freaking out about the procedure. I am so worried about what they'll find (I really don't have any symptoms of cc, except some discomfort around my hip, which I think is muscular). I have worked myself into an absolute panic.
