Hi! Apparently it does for me too and I've had foot pain and a kidney type stone but it wasn't located in my kidneys. It was in my saliva gland, under my ear. Weird, right?! Not sure, but I think I was getting way less water than I should have and was drinking lots of coffee and tea and some Diet Coke to compensate for the fact that I wasn't eating carbs. I was also eating giant portions of meat. In the past year, I've learned to reduce my meat intake to a moderate level and I drink a lot more water. That must have been the be cure for me because as long as I keep that up, I've had no problems.
