Hi, I had a hard bump about the size of a pea on my scrotum that was visibly dark underneath the skin. I squeezed it like a pimple and, after putting on a lot of pressure, it popped and shot a large amount of blood all over the place but nothing more. After cleaning and looking the lump is much smaller but only continued to bleed a little bit. There was no pain when touched and I have put neosporin on the now popped lump. What is this?
