my 5 year old son is having stomach aches in the afternoon, from 4pm. He eats a good diet, and plenty of liquids. He ends on rolling around on his bed in agony. Been in hospital for 3 days, doc s have mentioned appendisitus but ruled that out. One doc mentioned Cealiac Disease but another doc said no, and we ve been sent home, saying it s mild conspipation, but I m not so sure, as he is pooing. Help?!
