I've had verrucas on my right foot for 13 years!?

I've had them frozen off 33 times, surgically removed twice, pared off every month by a chiropodist for 2 years, used salicylic acid daily for years, tried a verruca stick (turns the skin black), had marigold therapy, homeopathic medicine and they have now spread on to my left foot! I'm at a loss, all of my kids have had them and they've gone with treatment. I have Fibromyalgia so am I stuck with these horrendous painful things forever? I have over 50 on one foot and about a dozen on the other. Any suggestions would be gratefully received!
