Nick from Alabama is unsure what caused this blister, but he believes it is a bite. The blistering could be anything from a burn to a spider bite and if it grows, deserves a trip to the doctor. Burn blisters don't grow after a day, but bites can. Nick says he is "self-treating" this blister and it is "getting better." I'm not sure what that means, but I would keep an eye on it.
