I just remembered my dad's planter's wart. He had a planter's wart for more than 20 years! He just kept treating it, but it never went away. My dad hates going to the doctor so he never went. A couple years ago he got a big piece of glass in the bottom of his foot. He tried pulling it out, but didn't get it all and when it got infected he finally went to the doctor. When the doctor was looking at his foot he saw the wart. The doctor got the glass out and got rid of the wart too.
