I just came from my doctors. He has schedualed 3 tests that I really need to know more about. Please excuse the spelling errorsColonscopic: I assume that is with the camera inserted but tell me what it feels like, how they prepare, anything you are willing to share.Colon biopsy: know nothing about The 3rd one I don't know the name but they stick a camera down your throat and inside the camera is "dye" to get a better look of your insides.If you have had these done PLEASE tell me about them. I don't know enough and talking to someone who has had it done would be helpful.I am terrified of hospitals, and a biopsy most likely means I have to go under right, well that is my second most fear. The more I know the better.
