MODERATE ABDOMINAL PAIN & PALE STOOL

MY 12 YR OLD IS HAVING MODERATE ABDOMINAL PAIN EVERY TIME SHE EATS & ALSO HAS CANKER LIKE SORES IN HER MOUTH ALONG WITH CHANGING STOOL COLOR. SHE HAS BEEN TO THE DR WHO TOLD ME TO GIVE HER ZANTEC WHICH I HAVE, BUT I HAVE NOT SEEN ANY IMPROVEMENT. THE PAINSHE IS HAVING BEGINS WITHIN MINUTES OF HER EATING, BUT SOMETIMES AFTER SHE EATS. DOES ANY ONE HAVE ANY SUGGESTIONS. I THINK IT COULD BE CROHN'S.

If that is all the doctor did, then you need a new doctor.  Did he do stool samples?  I would get her checked again because it sounds like pancreatitis.  Also, have them check for giardia, is she nauseated at all?
