I ignored one for a while hoping my immune system would best it back but it started spreading.

Podiatrist insisted on acid+ cantharidin (blistering agent) + trimming it out. We did that about 6 times, very painful,  didn’t work, took 4 months.  It was a very persistent wart.  Finally he threw his hands up in exasperation and wanted to do twilight surgery and really get in there and cut it up.  All along I asked to freeze it off and take the protein pill that makes your immune system attack the virus, but no joy.  My foot was a painful bloody mess for months.

I paid that fool a specialist copay for each occurrence adding up to nearly $1000.  I cancelled the surgery when I learned it was going to cost me $3000+.

I went to the dermatologist and they agreed with my cryotherapy + pill approach, paid $30 twice plus $6 for drugs and done.  And no pain except for a few seconds while the gun is freezing off the nerve endings.

YMMV but the home treatments did not help me.  Freezing plus pills worked for me and a lot quicker and less painful than acid.
