okay this is really crazy but I used to have one on my thumb by the knuckle. What I did is probably not highly recommended but nothing else seemed to work. I ended up peeling as much off as I could and then took a lit inscent stick and stuck it to what was left. I let it burn for a while it hurt bad. But it still hasn't come back to this day and that was about fourteen years ago!
silver sulphide or nitrate (I cannot remember exactly which one) is a cream helps in the removal of warts. In my country you can get it without a prescription, so make sure to ask your pharmacist or doctor about it. It isn't expensive.
clear nail varnish works because it kills it but it takes quite a while but they don't come back and you have to put it on in the morning and at night if it a week end u have to put it on in the after noon as well
You can go to a store like walmart and get wort remover stuff. It will go away. I got liquid stuff and it went away in like 5 days.

Duofilm is also a product that helps for the removal of warts.
