Hardcore Warts

So I've had these same warts for probably over a year now, and THEY HAVEN'T GONE AWAY. I have one on each thumb, and after many, many, many treatments, they're still there.
I've tried everything, the home wart removal kit, the freeze treatment at the doctor(over 15 times probably) and they have even cut them off, only to come back. By the way, those damn freeze treatments are one of the most painful things you will ever feel. It's -398 degrees of Liquid Nitrogen directly on your skin. The pain doesn't go away for a few hours. So other than just going to the doctor religously and experiencing this overwhelming pain, do I have any other options ie. surgery, that aren't painful. My doctor says she thinks we can have them gone by the end of the year, but I don't see it happening, and it hurts too much. What's my play?
