My wife had several plantar warts surgically removed from her feet a few years ago. She tried for a while to get rid of them with remedies from the stores, but none worked. She finally went to the podiatrist and had them cut out. We were actually talking about this the other day, as she thinks one may have come back. The podiatrist said this could happen if they didn't cut down far enough to get the entire root. I think she is putting off going due to the memories of how painful it was for a few weeks after they were cut. One hole was a little smaller than a dime and like a quarter inch deep. The podiatrist said she most likely got them from the pool she had to go to daily while working a summer camp. Needless to say, she/we never walk barefoot around damp/moist surfaces anymore. lol
