You could try taking the homeopathic pill Thuja, or, and this seems quite bizarre, putting banana skin on the verucca. My little boy had a hideous one and the lady at the chemist suggested it. I used to punch out a circle of banana skin with the end of a straw and tape it on, changing it every day. It must be something to do with the enzymes in the skin. The gaffer/duck tape thing seems to work too. My (obviously hideously infected!) son had warts on his thumb and fingers and the doctor suggested this course of action which I thought was a bit odd. I put the tape on (I was told put on for 6 days then have a day off - repeat and in two months they may have gone). Bearing in mind we're talking about a 7 year old fiddler the tape lasted about three days. I didn't bother reapplyng it, but hey poncho, the warts have dissapeared! Coincidence? don'y know, butt no harm trying - and you don'tsee the tape on the feet. Good luck.
