Two years ago I developed this skin-colored bump on my chin. I thought it was a pimple, but after squeezing it would never pop. Nothing would come out, it would just bleed and be there the next day. I got so mad at it that I squeezed with all of my might and it bled alot and scabbed up and went away. Then about six months later it reappeared. It doesn't change size or shape or color. I thought maybe it was a wart, but it hasn't spread anywhere else. Does anyone out there have a clue as to what this might be?
