I have an eraser sized lump on the bottom shaft of my penis. It seemed to show up after I tried shaving one time, so I figured it was an ingrown hair. However it's been weeks now and the lump remains. It is somewhat hard to to the touch, I can only describe it as feeling as though there is a ball under my skin right there. I have tried popping it with sterile needles but have had no success. The lump does not hurt but it is somewhat red and very unsightly. What could this be?
