Blister in my mouth: Popped it.

Last night cooking I guess I took a bite of something hot, because I felt a blister in my mouth up towards the front right afterwards. I felt how round it was, then pressed down and moved my thumb and the liquid outwards till the blister popped, and right away I could taste the salty liquid inside, like a kind of salty meat broth, only more metallic, like blood. The flap of skin came off this morning when I was brushing my teeth. I got it out on my finger and looked at it, then ate it.
