I have an anyoying wart on my ear. I have waited three months to see if it is a quick disappearing one, but no such luck.
It’s notin the ear caldera, more on the outer rim. You know the groove that on the outside that goes from about 11 o’clock to three o’clock on the edge of the ear? It on the bottom(stiff) portion of that not the upper more flappy piece.
I am a bit cautious of using acid or freezing near an open hole to a sensitive instrument. My thought is that the salysilic acid is probably safer, but longer taking.
