I had a few warts on fingers when I was 22. I went to a place were they had a device that could freeze them. The device has a small metal cylinder that gets really cold. They cut away as much as they could with a scalpel (this doesn't hurt or bleed if they do it right), and then they held the cold cylinder to the wart for a while. It took a large number of treatments (around 12 I think) before they were completely gone, but the final result was great. My fingers looked as if the warts had never been there, and the warts never came back.
