Noticed my 4yo had a swollen neck today - no pain, tenderness or stiffness and he's generally in great health. Seems to have come out of nowhere and when feeling it it's not like one solid mass, I can feel a few of his glands there and it's obviously a swollen area.
I'll be going to his GP tomorrow, any suggestions of what I should ask for or be concerned about? I'd rather be informed, I just don't know what to look into.
