Oh wow see with your eyes if you please lol

Okay excuse my tongue I’m eating Mac n cheese, it was kinda already white. But i got canker sores/or sores in my tongue, I got them like five days ago. I believe the top was is healing, but I could really use some ideas on what it is? I am addicted to icecream and I have been eating salt n vinegar chips then red,blue, and white popsicles straight out of the freezer. I look up at google, and they say ulcers/canker sores. But like I get canker sores but not really on top of my tongue ya know? Unless I hurt it. At first it was red, and I just kept eating the ice cream, it looked like a swollen taste bud and busted. But hey hope u guys have a good day and thanks for helping out!
