Blister?: Sounds like a blister, which could have occurred in response to friction on that area of skin yesterday. It stings because that thin layer of skin was protective of the inner layers of the skin, which are now exposed and very sensitive. If you start getting more of those blisters, though, go see a doctor immediately. If it's solitary and goes away, then should be fine.

Blister: Perhaps a blister from an insect bite but could be many other things. A picture and more information would help
