My 11 year old daughter has had an ongoing problem with dizziness and naseau since last august. She has had blood tests for mono, inflamations, anemia and thyroid, all of the blood tests show that she is fine. She has also had a problem with swollen lymphnode and the left side of her tonil is larger than the right. She is seeing a gastroenterologist and taking tests to find out if this is the problem. She is also taking prilosec daily but nothing seems to help. She denies any stress our depression. We have no idea as to what to do next? She has missed a lot of school this year.
