My ten year old daughter has chains of lymph nodes down both sides of her neck and into the area behind her clavicle bone. The nodes are the size of marbles and are hard and rubbery.she also has regular headaches as well as intermentant sore throat. She often has very little appetite and tires easily. Her neck is sore and swollen on the outside tonight and her throat is sore. She has an appointment with a ENT next week and has been on antibiotics. The nodes have been this large or maybe a bit smaller for months. Should I insist on her being seen tomorrow?
