Sometimes no dx is the worst thing to deal with -and annoying as all get out. Plus pain 24/7 to boot.

Have you considered any alternative therapies?
Like the hands on body workers /healers - drats my mind is a blank on the names right now....many of them have books in the library....if I recall some names I'll add them..

Or perhaps an expert and high rated chiropractor - if only for a comprehensive evaluation of you & your records /films?
