Just kind of an FYI....my son Levi did this very thing....they ran test after test and one test was for food poisoning...showed nothing! Then they did a test where they run a tube to the intestines from the "lower region" and see if there's a tear but it doesn't hurt them!!! Then they made him drink some kinda liquid and put him to sleep so they could watch it run it's course...THEN, re-tested for food poison, and were fixing to put him to sleep to do a laparoscope and BOOM! Came back positive for 3 types of food poison (he actually got it from the sitters~sitters hubby ran a chicken house and the types he had were from "run off water" from the houses"... SO.....it's going to be ok!!! It's probably something really simple....and besides, we will pray ALOT for yall !! GOD BLESS YA!
