Hi.Iam 56 yrs of age.I ve been having this health issue. I ve see sseveral drs.the question I want to ask is.I ve been treated or should I say.I developed this spot right center on my right heel.it started no bigger then a pin.very small.now it s about two inch circle. This one Dr said it was a so called verruca.he tried a burning it with some kind of clear liquid. all it did was blistering it several times therapy. I ve even shaved the callous around it.and keeps coming bk.what should I do as self remedies at home.one more thing to mention. they did a biopsy and no cancerous issue.but the pain is so unbearable at times that pain meds don t help.
