Well for several weeks now I've had a hard lump on the shaft of my penis. I believe that it is a severely ingrown hair, but all attempts to remedy the situation have failed. Yesterday out of frustration I performed some minor surgery on myself with a needle in the hopes of popping the lump. For the first time in weeks I had some success, a ton of puss and liquid came out and the lump decreased in size but still remained. By the next day the lump was back to full size so I once again had to drain it. It has been two days now and I've been repeating the process of draining the lump with no end in sight. What should I do?
