Given all these other stories, mine should be believable.
In high school, I had a bunch of warts on my hands. Well, I eventually went to the doctor and just he just burned and scraped them so that I had about 6 big bloody holes in my hands.
Well, a couple came back. And one day I was looking at one of them and noticed a little brown “seed” in the whites. Well, I chewed the wart down and got the seed out with the tip of a knife. Like a week later, no wart.
I probably developed 4 or 5 more warts after that, and on every one of them, I used a combination of my teeth and knives to remove them.
IIRC, I usually would find such a seed, and it’s removal would cause the wart to go.
I still have small scars from the ones the doctor removed. I have NO scars whatsoever from the ones I removed.
