This morning, I thought I'd slept wrong because my back was killing me down where the vertebrae are that are deteriorating. As the day has worn on, though, the pain has traveled to my left side. Now I'm thinking it's my kidney. Anyone out there that has had kidney trouble... what does it feel like? What are other symptoms? My ankles have been swelling the last couple of days and urine is really dark; so far today, none. I was thinking maybe it is the lack of water pills? I've run out and no insurance yet. Any comments or advice? It "huhts"!!
