My 8 yr old sons tonsils stay swollen, the dr don't wanna take them out unless they causing problems. Well I checked his throat this afternoon and his tonsils have went down but I noticed three or four clear blister like things on the back of his throat. He says they don't hurt and I'm not sure how long they've been there. The biggest is half size of pencil eraser. I am making him a dr app but wanted to see if I can get any info just to ease my anxiety.
