Re: Swollen Lymphnodes
It is common for lymph nodes in the neck to enlarge with strept throat and repeated infections will keep the nodes enlarged as they go down slower than the infection itself resolves. A node over 1 cm is considered enlarged, so a lot depends on how big they are, how they feel, and how your child seems when he does not have strept throat. If he is pale, eating poorly, febrile or seems tired when there is no infection, I would be concerned. If he seems normal otherwise, less concerned. His WBC will go up during the infections, so it is important to eval his labs with the timing of his infections. His CBC should be normal when he is well, elevated when he sick. Nodes in the back of the neck are less common in strept, but do occur in mono, which can affect 3 year olds. I would ask the doctors to check his liver and spleen on exam if they haven't done so, and other places lymph nodes exist, just for your reassurance. If he keeps getting strept at this rate, he may end up at some point needing his tonsils out, which will usually clear up the strept episodes and the nodes will go down when there is no longer infection in his throat.
