I am a 35 year old black/white mixed male. In the lower right side of my scrotum, I have an unraised lump about jelly bean shape and size, unnoticeable from the exterior. I have had this lump for about a year, and it has always itched, I used to use Tinactin, but to no avail, I would scratch it so much that the skin would get very tender. I have always trimmed all of my pubic hairs, including the scrotum to shadow length. About six months ago I squeezed the lump and a yellowish puss came out of what appears to be nothing more than a pore, hardly visible to the eye, I would squeeze it until the yellowish fluid mixed with blood, and stopped squeezing when it was nothing but blood coming out, and the lump would end up 1/3 its size. i've been doing this for about the last six months, and now the fluid comes out of 2 pores. When I squeeze the lump in the shower when I wake up, it starts off at about the size of a jelly bean and then goes to approximately 1/3 of its original size. I also noticed that if I skip a day, it can get to the size of a shelled peanut, and when I squeeze it, it drains dramatically and has an odd smell that I can only compare to the smell of intercourse. I am unemployed and do not have insurance. What could this be, and what should I do?
