Sore Small Wound On Hand

It's only about the size of 1/4th of a kernal of corn, near the base of my thumb, on my hand.. I wondered if it could be skin cancer. It might be something from the accident I was in last Summer - a piece of glass in there or something. It seems to heal and leave a burr type thing sticking up, so I scraped it off and then it felt kind of sore. It just seems sore, more sore than a normal cut should be, but it doesn't hurt much, just more than it should.

I just put raw ACV on it and covered it in a band aid. Is this sound like a good idea? I was going to put garlic on it too, or urine soaked cloth, or even raw honey. What would be the best way to heal it up?

BTW - my leg wound closed up [healed over] several weeks ago. Tweet
