Re: ew. Warts. :(
The best thing would be to call a doctor, arrange an appointment, and have them removed with liquid nitrogen. It will take 2-4 applications to get rid of them, and you can only get 1 application a week. There is over-the-counter treatment, but it doesn't really work.
There really isn't any way to prevent warts. Just to remove them.
I hope I was of some help.
My toes are cold.
