My one year old has had bronchitis for a week now.. I just noticed a lump at the base of his skull, not quite on his neck.. You can't see it, just feel it.. It feels like the size of a pea and you can move it about slightly.. It's only on the one side.. Should I have it checked out?? Do you think it could be a swollen glad from being sick? Should I wait to see if it goes away when his bronchitis clears up?? Any input is welcome! Thanks a bunch..
