My 7 year old daughter is 4 feet tall and is 61 pounds. Exactly one week ago she came home from her second day in first grade and said her stomach didn t feel good. She vomited several times, but no diarrhea. After a rough night of vomiting and stomach pain, she woke feeling better and went to school. She had a normal day, but started feeling sick again when she got home. I took her to the emergency room. She did not have a fever. They checked her, tested her urine and blood. The test were negative. The doctor said she had a virus. They gave her a pill that dissolved in her mouth to help ease her upset stomach. She had had this medicine before, but this time it did not work. In fact, it seemed to have the opposite effect. They gave her a shot to help ease her upset stomach. That worked and she drank to get rehydrated. I kept her home from school the next four days through the weekend. The shot the hospital gave her for her upset stomach wore off and she started feeling nauseous again. Our family clinic suggested we try a gel that she rub on her rest. Again it had the opposite effect. She feels fine each morning and can eat, drink, and feels normal. But by late afternoon to early evening, she gets sick again. This has been going on for a week now. No one else is sick in the house. Is this a virus?
