Hoping someone may have experienced this sensation. The CAT scan showed no more intussusception but I still have this intense burning in one spot about 2 inches from my upper belly button. It isn't like a generalized burning but pinpoint burning. I have an endoscopy/colonscopy scheduled for Tuesday so I hope they figured it. Can the pentasa or entocort give you an ulcer. Maybe that's it. Never had anything like that though.
