Hi, and keep your head up!
One of my close friends had this shit in his kidneys! He works at the garage and fixes cars and one day he just passed out, in the middle of his working day! Then he had to spend a whole month in the hospital. The problem was - that this kidney stone has stuck in his ureter and there was a possibility of operation, to cut this fucking stone from his penis! Happily, everything went fine!
Wish you good luck and feel better
p.s. my advice - drink clean water to avoid this shit!!!
