urinary tract infection
"I have had a urinary tract infection since January and it is now March. First I was put on a Z-pak with no relief. Then I was put on Cipro. The test came back as if I hadn't taken anything. Now I am on nitrofurantoin and the symptoms have subsided. I have a headache and am tired but so what they will go away when I finish taking this. It worked great for me."
