skin sore that won't heal
I have a sore on my little finger that won't heal. I did not hurt it (scratch, cut). It just appeared a couple of months ago. At first I ignored it.
I have put neosporin on it for days, and also kept it soaked in tea tree oil, but it does not affect it. The top skin layer is gone and it looks reddish. Before I treated it it was not red and had a layer of dead skin or something.
