I bet its a kidney
problem. I had that about a week ago, hurt sooo bad. do you have these syntoms.
1. Frequently having to go to the bathroom
2. When you go to the bathroom and you're all done, does it feel like you have to go more, but you dont?
3. Lower back problems
4. hurting when you go pee.
if you had these syntoms, dont wait, go to the doctor right away! I waited because i thought that it was just like i twisted somthing in my back or slept funny and i suffered.
