question: My son, who just turned 8, will have vomiting and diarrhea around 4-6 a.m. quite often . We narrowed it down and thought it was chicken nuggets from XXXXX and other restarurants. It would coincide with that. He could still eat chicken if we cooked it. He cries with abdominal pain and the stool is light and somewhat grainy looking. It occurs without warning. He has respiratory and skin allergies, but does not break out into hives during these attacks. Any ideas?
