if your gums and lips are bothered when you get it?
My ds (5.5) has tonsillitis and his gums look really red and swollen. He has a large blister on the front of his tongue and a small blister on his lip, which looks swollen.
I have had tonsillitis many times myself but can't remember having any of the above problems.
Have looked on a few web sites but none mention these problems.
TIA
