Burnt tongue?

I am hoping I am not the only one who has had this issue.. went on a bit of a binge over the weekend. Drank a lot and, of course, smoked a bunch of cigars. I tend to smoke fast and down to the nub so I get a lot of heat. I burned a spot in the center of my tongue. Its like a little blister and its white.

Anybody done this before? Should I be worried? Anything I can do to speed the healing?

Thanks!
