So basically, my shoes gave me blisters slightly on the inside of the heel that immediately broke leaving the blister exposed. The epidermis in this area is very thin and I need this to heal as soon as possible because of a dance class I'm taking, (and the fact thay most facets of my life have me on my feet for a while) and as of now, it hurts to even walk barefoot. What would be the best way to take care of this to cut down on pain and promote healing?
