I just wanted to mention that I may have given the wrong impression by referring only to McKenzie 'exercises' like it was Pilates or something. It's more precise to refer to the McKenzie Method, since it is more a diagnostic approach to troubleshooting back pain in general. There are exercises to be sure, but only if it's determined if they can address your specific situation, and which ones you do depend on what your specific problem is. In no way was I suggesting to do them blindly or without the benefit of traditional diagnostic medicine through your regular doctor.
I got MRIs with and without contrast, as well as x-rays, ultrasounds, etc, and was shuffled from specialist to specialist. I knew I had no interest in risky surgery except as a last resort, and I also knew that many prematurely jump into surgery that introduces new problems without fully addressing their original problem. I also wasn't interested in taking (mostly ineffective) painkillers forever either.
I was determined to be fully informed before making my decision, and that included an exhaustive search of legitimate alternatives (not to be confused with 'alternative' quackery like homeopathy and the like, and I put most of chiropractic in that category as well.) The McKenzie Method is the only thing I found that worked, and I was upset that none of my doctors ever considered it (or even knew about it) during the many many months they 'treated' me.
After very carefully working through the McKenzie book's diagnostic steps myself, doing the recommended exercises and postural changes for sitting/sleep/etc, my pain started to centralize and disappear as described
and then I was pain-free in a week! One f*cking week later after all that time of ever-increasing suffering...what a strange simultaneous feeling of relief and frustration!
Of course, testimonials like mine are in no way a form of evidence and should always be regarded with skepticism (the plural of anecdote is not data

) However, they can certainly be useful as a guide for where to do further research. Go and listen to your doctors, but don't passively leave it up to them to solve your problem. They just move onto the next patient, while you have to live with the consequences of your/their decisions for the rest of your life.
