What's on my tongue?!? TMI, maybe? Pic included

Im sorry everyone, I'm freaking out right now... Yesterday I attempted to eat a cookie that was still scalding hot! It burned my tongue and I spit it out. I immediately drink some milk to soothe the pain. After a while a bump appeared. I figured it was inflamed from the burn or a lie bump. We'll, this morning, I woke up and decided to look at it because it is extrememly painful and this is what it looks like. What is it? Thanks everyone!
