Aww wow.. Well in my moms case.. When her infection started;
she was in the bathroom for hours trying to pee but it wouldn't come out, and her bladder was about to explode, so she tried to let out the pee slowly but it wouldn't come out, and when it did it hut like hell, then she would shake now and then, having like small seizers or something and we were going crazy we didnt' know what was happening. And she couldn't really stand up straight she was in so much pain.
Me I never had a kidney infection but I had a uterine one.. And if I didn't treat it my baby would be born with a kidney infection.
I hope u get to the doc's soon.
