I watched some tv last night with Mr. Lover, and when I stood up, my back was KILLING me. I went to bed, and when I woke up, it was the same. It is lower back pain that hurts whenever I do anything that requires some core strength - sitting down and standing up from sitting, picking something up, not being...straight up and down and facing forward.

I have never had something like this. I took some painkillers and am icing it, but does anyone have wisdom to share?

Note: not a fever/kidney problem. BEEN THERE.
