The whole body is interconnected in ways that may be difficult to comprehend. I'm also going to a specialist because of my back. He's probably very competent because he's been working with some high profile athletes (Like some US top football players)
His claims is that it all starts with what you eat and drink, and you may get problems with muscles if the PH balance in the stomach is wrong. Basically that means you have to eat and drink less of some things, and unfortunately these are the things that are good, like red meat, coffee, alcohol.... Darn!!!!
Everything that swim and fly is fine (Any kinds of fish, chicken++)
And drink a lot of water, I mean heaps of water
This may sound like a joke, but it's certainly not... It works, especially the water thing.....
