In the middle of my scrotum, on that line that runs down the middle, a little to the right of it but basically right on it, there was a bump that felt sort of hard, so i scraped it off with my nail, and the skin stayed raw for a few days. Now a yellow scab has formed and I have put neosporine on it and it gets smaller and smaller everyday, I am worried this is a wart, is there anything else this could be ?
