Its currently forming a boil so no chance of infection yet. Though if it pops, Ill definately clean it, rub any and all burn cremes I can find on it, and bandage it up. Though it was a very minor burn to begin with.
It should not be a boil (a yellow filled zit) if it is get to a doctor PDQ. It should be a blister that is only filled with water, this normal. It will pop in a day of two and the skin under it will be a bit red but nothing to worry about.
