N8torius, thanks for your thoughtful reply. I concur that subluxation theory is bunk and ought to be abandoned.
There is substantial evidence for NSAIDs, muscle relaxants and even some tricyclic antidepressants in mechanical low back pain. There is not evidence for narcotics.
I disagree with your recommendation of rest. There is evidence that it tends to prolong pain and disability. Bigger fan of physioball use.
...anyhow, I agree lots of docs take credit for the self limiting nature of many diseases and injuries. I recall it referred to as, "masterful inactivity."
