urinary tract infection
"Although it was expensive, it was well worth it.  My interstitial cystitis had gotten so bad it hurt to walk, I had to keep an ice pack between my legs.  Within one dose of this, I started feeling better. The one thing I would suggest is that the pharmacy put a warning on the bottle stating specifically that the medicine will possibly turn your urine blue/green.  The first time that happened, it was quite shocking!  Overall, this medicine really saved me when the other ones let me down."
