My baby boy has had swollen lymph nodes in the back of his head for a few weeks now. Almost a month..I had him seen at the doctor, but the PA we saw, who I trust, says she thinks it's just from him teething. It's really bothering me, pretty badly. I don't want to take a single chance with him..Swollen lymph nodes in the head in a baby can indicate terrible things....i.e. lymphoma and etc. I am going to have him see his actual pediatrician this week and have him order a CBC. I'm not taking chances anymore. Too much cancer in my family, and I have too much to lose.
