Absolutely. I had some and they were zapped with
nitrogen. But, instead of a swab dipped
in liquid nitrigen, it is a pressurized form of liquid nitrogen that is released as very cold spray from a bottle. Pretty much like those one-dose-nitrogen to burn foot warts sold at the pharmacy. They are identical. The idea is to burn it and as the skin grows back, the wart falls off. May need many checkups to see if it worked entirely.
Except for the pride on the moment, it doesn't hurts that much.
