A few days ago my tongue started hurting and then I ate some dessert and over the course of some days the sore kept getting worse. It got the worst today and now it hurts when I eat, drink, and talk. It even hurts right now. The pain even spreads a little to the back of my mouth and it also hurts in my right ear

i've been using peroxide mixed with water and swishing it around for a minute for a couple days and it keeps getting worse. But the last canker sore I got, it worked, and that was a couple months ago. And, peroxide heals microwave burns in my mouth

i heard only little kids get canker sores. Maybe I don't have a canker sore and it's actually something else
