I found that the prep gave me a similar pain to when I went to ER. Like Cat says, I think the scope and prep can cause your symptoms to flare up, but if you get anythimg different you should contact the doctor (did you get a helpline number after the scope?). As for abnormal mucosa, I think that is the body's reactions to inflammation or irritation of some sort. Mucos is snot like stuff, you have it there anyway but you don't really notice it. But if something's wrong you get more and its thicker. As for looking at the
small intestine, they must have got a peek at it as the terminal
ileum is the very last part of it. If they need to, they can use an ultrasound, CT scan or small bowel follow through to image the bowel from the outside, or a pillcam to have a look inside. Have a look at
