What this is not: a book about one specific condition, injury, or surgery.
What this is: a guide to dealing with the common factors of many musculoskeletal conditions, inflammatory diseases, and their consequences.
Dr. Warner takes the opportunity to address the whole patient—presumably: the reader, though it could equally be a reader’s loved one, or even a reader’s patient, insofar as this book will probably be read by doctors also.
She takes an “inside-out and outside-in” approach; that is to say, addressing the problem from as many vectors as reasonably possible—including supplements, diet, dietary habits (things like intermittent fasting etc), exercise, and even sleep. And yes, she knows how difficult those latter items can be, and addresses them not merely with a “but it’s important” but also with practical advice.
As an orthopedic surgeon, she’s not a fan of surgery, and counsels the reader to avoid that if reasonably possible. She also talks about how many people in the US are encouraged to have MRI scans for financial reasons (as in, they can be profitable for the doctor/institution), and then any abnormality is used as justification for surgery, to backwards-justify the use of the MRI, even if the abnormality is not actually the cause of the pain.
Noteworthily, humans in general are a typically a pile of abnormalities in a trenchcoat. Our propensity to mutation has made us one of the most adaptable species on the planet, yet many would have us pretend that the insides of people look like they do in textbooks, or else are wrong. The reality is not so, and Dr. Warner rightly shows this for what it is.
Bottom line: if you or a loved one are suffering from, or at risk of, musculoskeletal and/or inflammatory conditions, this is a top-tier book for having a much easier time of it.
