Cipro
"I had kidney pain . Back back. Pain that went down to my leg and I couldn't sleep. Thought it was from maybe over drinking so drank a lot of water but 7 days later of eating only vegetables and fruits and taking cranberry juice and anti oxidants I went to the doctor . After my first pill the pressure was gone and after the second pill (500mg) the pain was gone. It works!! No side effects other than slight nausea but that's nothing compared to one week of pain and sleepless nights."
