two weeks ago my daughter was sick with what seemed like a normal cold last week she seemed to be feeling better so i let her go ahead and attend school however every morning shes been complaining that her throat hurts. but the symtom normally went away within 30 minutes after she got up in the morning. Now all of a sudden this morning she woke up crying and saying her neck hurt when i looked at her her lymph node area on the right side of her jaw line was the size of a golf ball and the other side was not far behind i took her to the doctor and it came back negative when they did the test so they just perscribed her some antibiotics and sent us on our way. my question is what might be the problem?? because she really is in alot of pain and i have no idea what to do. :'(
