You can always get some dry ice and burn it off yourself. It hurts for about 5 seconds until your skin is basically frozen. I did it just once after months of acid treatment at the Dr’s. Just get it on the wart though…press real hard and prepare for it to turn black and need to be “pulled” out.
I’ve been trying the nail polish thing for a couple of days now. It looks like it’s starting to get “sickly”… most of it is white, with black spots that are taking over the wart slowly but surely. I’m just hoping this works 'cause I really don’t feel like attempting to pull it out again. I bled too much last time to want to make another attempt. When I come home for the holidays, if it’s not fallen off, I’ll probably slice off a piece and then apply duct tape or more clear nail polish.

The nurse sent me a copy of the article with the duct tape method. Note: I am not a doctor! I am just quoting from the article. The article in question came from the “Breaking News and Commentary” section of “Infectious Diseases in Children,” November 2002:
“Those in the duct tape group were told to leave the tape on for six days, then remove the tape, soak the area in water, and rub the wart with an emery board or pumice stone. After 12 hours without the duct tape, they were told to put a new piece on the water, and continue the cycle for two months or until the wart was gone. If the tape fell off, the patients reapplied a fresh piece.”
According to the article, “85% of the duct tape patients were wart-free at the resolution of the study, compared with 60% of the cryotherapy group.”
Glad the nail polish is working 
I think probably anything that suffocates them works.
I should try the duct ape method for this wart on my knee. I’ll hunt up the duct tape and see how it works.
I had one removed from my hand at the campus clinic in college. They rubbed some liquid nitrogen on it for a few minutes (at a charge of something like $5) and told me to keep it covered. A week or so later it was clearly separating itself from the skin around it, and a few days after that I peeled it right off, as you would a scab (but this was painless). This was about 12 years ago, and I’ve had no recurrences.
I seem to recall reading something about the duct tape thing as well, though; let us know how that goes.
