bladder infection
"I am 65 and in good health.  I don't take any medicines except aspirin.  I do get bladder infections every once in a while.  I was given this medicine and had a terrible reaction.  My whole body would start shaking like I was freezing or standing outside in the snow with no clothes on for 10 minutes.  I would do everything to try and get warm and keep my teeth from chattering but nothing helped.  I couldn't walk right, it was like I had palsy.  The only thing that gave me relief was taking two aspirin.  In about 20 minutes the shaking would stop. I went back to the doctor and he couldn't figure what the problem was.....well I'm allergic to this medicine."
