I recently found a pebble sized lump on the bottom of my left testicle. It feels like a rock that got lodged in there .It feels tender to the touch too. I have back pain down in my lower back but I have always had back problems and can't really say what has caused this recent onset. I am panicing! I have no insurance and no money either. What do I do? How do I get insurance? If I can't get insurance, then how do I pay for the obviously vital examinations and what not?
