HP...I hope all goes well tomorrow. I hope they will be able to tell you something about what seems to be ailing you. I know it is frustrating to be in pain and not feel well and not have a clue why. The colonoscopy didn't seem like to bad of a procedure. My husband had one like two years ago. They put him to sleep and when he woke upo he felt pretty good. He wasn't sick or groggy at all. In fact the first thing he said when we left is head for Subway.LOL He ordered a huge sub sandwich and ate the whole thing.
