Kidney Stone
My poor Secret Pal!!! I'm going to join in the chorus and tell you that I've also had these...when I was about 16 or 17. I don't recall the reason, I want to say too much calcium, but I could be wrong about that, try Web MD, they're pretty good at this kind of thing...I was actually in the hospital with mine and I can recall passing it, that was a weird experience. I send you love and healing prayers for a quick end to this!!! Your very own SPinSC!!!
