Hi,
I had the exact same diagnosis on my colonoscopy. The biopsies went to the lab but they all got lost!! So angry and frustrated! I then had a MRI scan & ultrasound both came back normal. I then went for another colonoscopy, the ulcers had dissapeared but I had an erosion.. My consultant still hasn't diagnosed this as chrons as he says he doesn't have enough evidence but still suspects it may be early stages.. So frustrating hope you get sorted
