urinary tract stones
"I felt like someone hit me in the back one day, it throbbed and felt swollen. It bothered me for a few hours. Two weeks later I couldn't pee and it hurt so bad I went to ER. They did cat scan to find a 6mm kidney stone in my ureter.  They started me on Flomax. I followed up with my doctor and 2 weeks later I passed it with no pain except a little pain when I peed.   I don't know if it were the Flomax or chanca piedra that I bought did it  But it was painless and I was so worried.   Now I will take it to my doctor to be analyzed."
