question: My 6 year old girl is lactose intolerant, she is a really good eater with a healthy appetite. On saturday she had stomach pain and vomited, she has since had stomach pain ever since and doctor said glands in her neck were up, on tuesday she started with foul smelling watery diarrhea, she is still having loose stools, foul smelling flatulence & her stomach is very swollen. She seems well in herself but is refusing to eat and gagging, she has never lost her appetite before.
