I wanted to know if stopping drinking soda pop can throw your kidneys into shock. I stopped drinking pop 5 days ago mind you I was drinking up to 6 ltrs a day for years. I can hardly walk don't know if it's kidney or if my back has gone out. Please help.

It can be a total chemical imbalance.

There is no telling the damage that drinking so much soda for years has done to your body. If pain continues, see your doctor
