I suspect in the end it was a yeast infection, and when I tried to clean it I must have irritated it so bad it developed a puss pocket, or ooze pocket. It slowly went away, I used peroxide and gold bond on it daily. Whatever the lump was must have burst, because it slowly began to leak fluid, so slowly that you would never know it was draining. But I would get dried up stuff in there so I knew.
I am thinking maybe I got it from yeast on one of my bullies? Maybe I was playing with one and then had a belly button itch???
