I've learned that the back affects all other parts of the body or can affect how the intricate connections the back has with the whole body influence how well one feels.
I came in with a strained shoulder from catching myself during a stumble and a swolen ankle. I had my back worked over, my foot and ankle manipulated/stimulated and the nice gal told me about pure cherry juice, which I already knew was right for my gout.
A few days later and I feel better all over.
Four stars/five stars...blah blah blah. The real difference is that my pain is improved so I am not seeing stars, LOL.
