I feel your pain. I had them for 10 years all up and down my arm. I never gave them much thought but when they started spreading, I wanted to do something about it. I tried freezing, scraping and a whole host of other painful ways to try to remove them and nothing worked. Finally, I read that Oil of Oregano is a powerful anti viral so, I started it (you want the wild with a high percentage of cavrecol) and within 2 weeks they were completely cleared up.
I've since heard that Olive Leaf is a better antiviral but, the Oil of Oregano worked for me.
