The roughness of the surface on the red area is bothering me. Now that I think about it, it feels like the beginnings to the scabrous area on the warts that I got rid of, you know, when I first started applying the apple vinegar. I've made another decision:
More vinegar. I think the wart virus is still around, and if that's the case, I'm probably better off applying more weak acid now, to get to the virus, as opposed to waiting around and essentially starting from the beginning again. I don't want to go back to square one and wait another 16 days.
I take the cutter knife, sterilize it again, and start getting rid of the rough surface that's covering the red area. I think I made the right decision.

The red area is not so red anymore. In fact, in some parts, it's actually very white--is it fat? Skin? Thin pockets of warts?--especially around the depression I noted in the past couple of days.

I'm pretty sure the job is not done. More vinegar, cotton balls, and band-aids to get rid of the remaining suckers.
