I have what I believe to be a sebaceous cyst on the side of my penis. Obviously not a great place to have one so I decided to try and remove it with a knife tweezers and a tiny pair of scissors(all sterilized). After being in there I discovered that there was no puss but it almost looks like a bunch of scar tissue. I decided to take as much of this mass out and it's healed just fine except for the fact that there is still a recurring bump. Not as big, but still pretty noticeable. Any ideas?
