I know this is a crazy question, but it's way too coincidental. I am an avid Diet Pepsi drinker, might as well be given to me by iv. I sometimes drink milk, but pretty much the pop morning, noon, & night.
It seems as if whenever I start drinking more water, I have kidney pain.
Yup. Drinking lots of water makes my kidney hurt... I've had tons of stones and infections in that kidney, and just been diagnosed with possible UPJ obstruction, had a narrowed section of my ureter removed, and the entire ureter slit open lengthwise with a large stent put in, in hopes that it will grow back around the stent larger than it was. The doctors acted like I was nuts when I told them drinking lots of water hurt my kidney, though. (As does eating a large meal...)
