Should I be concern, my 3 year old son has a cysts on his neck, it s hard, firm but movable. He has two of them, one below the chin and the other on the side of his neck. I noticed it in August when he had ear infection. It s now Dec and the infection is gone and it s not gone yet.
Hi, From history it seems that there might be having enlarged in the neck and sub mandibular region. Nothing to worry, after infection subsides, lymph node might remain enlarged for some time or long time. Ok and take care.
