I had a UTI about a week ago, it was very painful to urinate and I was going like every 10 minutes to the bathroom, all the burning and pain is gone, but now a week later I have kidney pain on my left side... well I also had it when I was told I had the UTI except it was on both sides all over my back it was BAD, now its just on one side... Could this be more than a UTI, more like a Kidney infection?. I am going in tomorrow for another urine test.
