urinary tract infection
"This the only thing that relieves painful blockages and severe pain as well as lowering high blood pressure  sometimes caused by kidney stones. I have found nurses and  ER doctors and several emergency rooms and hospitals are not familiar with this drug so I make sure I have several pills on hand at all times. This may have saved my life last summer when nurses misread my doctors instructions and would not give me any during a severe kidney stone crisis. My blood pressure was off the charts. If I had not walked out and gone home to take this, I might not be here. My   doctor had gone out of town and he was horrified."
