My 8 year old had a 24hr bug last week and we thought it was over, was fine the whole day after the 24hrs went by then next day she said her stomach hurt and she threw up so we went to hospital all test came back neg. Now few days later she is having pains again and woke up at 3am with stomach pains and throwing up. But while i was in bathroom with her i noticed an awful smell....(like poop) i looked it up and im wondering if it might be what i found. That there is a destruction that is causes this and should i be worried(?) My questions is what do you think about her symptoms?.....pains around center of stomach, headaches, not feeling good, tired, vomiting.
