I have done 5 liver flushes, 3 colonics, have hiatal hernia, and the only thing that took away my back pain was flexaril, a muscle relaxer. You do need to do more Liver Flushes and other cleanses, but be aware about when you have the pain.
I you still have the pain when you haven't eaten anything all day, it could be your back. (possibly kidneys, but you would probably know that)
On the other hand, eating fats and proteins, if you have a GB full of stones can hurt pretty bad. Don't eat buttered popcorn! In my case it was both my back and my gallbladder, but after 5 flushes and three colonics, I feel much better when eating proten and fats thanks to curezone and the helpful people here providing such great help.
