New Hope for Sciatica

It's more about the how healing works in 3 parts: physical, chemical and mental. One cannot work without the other. So it gives a high level overview of all the things that might be the cause of the pain. And it's complicated! It creates awareness about underlying factors causing/worsening the pain, but it's all about contacting a professional.
So, there are no practical answers in this book, it talks about a few strategies but without diving in them too deep. For example: a diet with less inflammatory food suggesting ketogenic meals and intermittent fasting but it doesn't explain how that can be done.
