I could tell it was not a hair follicle, as I have recently had two warts removed that looked very similar. I decided to try
apple cider vinegar since to try
and figure our whether or not it was a wart. (i.e. put it on there and see if it turns white/swells/etc). So I did that, and it turned white and swelled up. So i decided to keep applying the ACV over night for the next couple of nights. It went just as planned at first, everything turned brownish black and started to die and scab.
