urinary tract stones
"I had a jagged 3-4mm stone in my right kidney for months. It wasn't causing much pain, but it was causing regular bleeding. I gave up on it passing on its own and finally went to the family Dr. expecting to hear that I would need a surgical procedure.  BUT, the Dr. put me on FloMax; and after just 10 days on this med I passed the stone with very little pain!  I regret waiting so long to get help with it.  The only side effect I had was the sexual dysfunction described, but it was so minimal it wasn't bothersome enough for me to stop taking the medicine.  And the side effect went away after stopping the medicine."
