question: My son is 14 years old and in good health. The reactive lymph node on the side of his neck was always slightly noticeable. Several months ago, it swelled and several others were also somewhat noticeable. All the swelling has come down and you would never know they were there. He has normal bloodwork. no signs of illness, and no nodes swollen anywhere else. His ENT says not to be concerned. Should we be concerned? Is there another kind of doctor you can recommend to go to? Thank you.
