I've always been a bit overweight, nothing HUGE just 20 - 40 pounds over, nothing big.
Anyways lately I've noticed a horrible pain down where my Kidneys are, It usually happens after I eat something fatty like Mc Donalds or Pizza.
At first I thought it might just be something that would pass but it's getting more common.
The only way I can describe this pain is a burning feeling or as if someone is grabbing your Kidney and scrunching it up in their hand.
I drink a HEAP of water, usually 4 litres a day or more ( I'm a very Thirsty Guy ) and my Diet is usually pretty good.
