Hi, I have recently had a wart taken off by cryotherapy (which I have done before), on the palm of my right hand. It has been about 2 days since then and a marble size blister has formed and causing severe pain in my hand, even without pressure. It is blue-dark colored and hurts very badly, however when I touch it, it feels like a normal wart. Can you please tell me how long this will last roughly? Thanks.
