My 13 year old daughter has been having sever stomach pain, vomiting, and bloody diarrhea. The stomach pain has been going on a few months. We thought it might be the start of her period but was not the case. Over the last week she has been complaining more frequently. There has been several puking episodes and some blood in her stool/diarrhea. We took her to the dr yesterday and they did a ct scan. They said her organs and white blood cell count was normal. Also stated that her lymphnoids we a little swollen. They thought it could be a possible virus. Since yesterday about 5:00pm she has slept, got up at 7:00am went to school, home at 3:00pm, and asleep since. Any ideas?
