My daughter is 8 years old and has been sick off and on for 2 months. Her symtoms are severe stomach pain, diarrhea, nausea. She has only had a slight fever during all of this. We were in the hospital for a couple of weeks with a diagnosis of pancreatitus. She was taking zoloft for a couple of years and the doctors claim that was the cause. When we were discharged, she was well for about two weeks and now she is sick again, but they can't seem to find out what the problem is now. Any advice?
