What kind of burn is this?

I was at a bonfire, and my friend moved a stick on the fire, and a smoldering (Not on fire, nor unburning) stick briefly touched my leg and burned it. That was yesterday. Then It was just red, and now (today) its sorta waxy/shiny, and there are like three red craters. It is about the size of a dime. What kind of burn is this, will it go away, should I be worried? If needed I will take pictures.
