My three year old daughter has had swollen lymph nodes in her neck since Thanksgiving of last year. They are very slowly getting larger and slowly spreading down her neck (it's on both sides, just behind ears down to collar bone). She is always sick. A cold, cough, fever that comes and goes (but is fairly mild most of the time), ear infection on occasion and the antibiotics never help. She hasn't lost any weight, but she does sweat pretty bad at night (or any time she sleeps). Sometimes she complains that her legs hurt, but I'm not sure if they really do or not. The docs keep saying that it's allergies (no allergy meds help at all) and that "Some kids are just lumpy." Three different doctors have said that "It's too early to be worried about anything weird like lymphoma or anything", yet since three docs have said that, I'm now worried that she could be seriously ill with mild symptoms. Am I overly worried or should I nicely demand they test her for cancer???
