Freezing Warts

Ok, so I know warts are gross but I'm excited that I found another way to get rid of them! I had a couple on my leg near the ankle. I heard it was from shaving, but I dunno. It was only on the one leg (left). I had one a couple yrs ago that I went to a dermatologist for. He charged me $75 to freeze it off, but a few months ago, it started to come back. I found an article on the internet about how to freeze them off yourself using liquid nitrogen ( DISCLAIMER:I don't recommend you try this at home, and if you suspect you have a wart, see a doctor/dermatologist). I followed that and successfully got rid of them, but I also had one on my thumb near the base of my nail that I wanted to get rid of. Unfortunately I was out of the liquid nitrogen, and I remembered that the computer compressed air cleaner would shoot a frozen spray if you sprayed upside down, so I sprayed some of it into a q-tip and applied it to the wart on my finger. A week later, I pulled off the scab and it was gone!
Ghetto, yes.... but when you can't afford a dermatologist - it works. The compressed air is also cheaper than the OTC freezing wart stuff and lasts longer. I'm all about stuff that serves more than one purpose and saves me money in the long run.
