Okay, shooting h2o2 directly into the wart via syringe was intensely painful for about a full minute, mildly discomforting for about 5 minutes, and then next to nothing afterwords.
There was an immediate whelt and swelling underneath the wart, obviously the chemical reaction and released oxygen creates this effect when under skin.
Today, now 24 hours later, I can see the dark discoloration of the wart that one would associate with the wart dying. So far, this looks like a success, but time will tell.
