I felt some acute pain while walking for a half-year or so. It was increasing over that time, so I went to the doctor. Doctor said it was a papilloma wart under the sole skin, so she cut off the skin with some milling cutter(no Idea what it is called in English) and then pour some acid (even the smoke was obviously visible!) into the wound. It was painful, but FAR from how I expected it to be.
I did a lot of wart removals. My method worked well enough I never had a repeat patient.
I’d make a ring of surgical lube around the wart to protect the surrounding skin and tell them “Let me know when it’s too cold to bear.” I’d hit it with a liquid nitrogen bottle until they say stop. Wait a minute, repeat. I’d do about 5 rounds right there and they never came back to see me.
Nice. Good to hear there are still some honest doctors out there.
