I also get my back adjusted, and I know what you mean. It helps for awhile, but I always end up with the same "fault lines" being tight and painful, sometimes after a few weeks, sometimes after a few hours (if I don't slow up enough while driving over a dip or something!) My latest game plan is to keep on keepin' on, taking my pain meds if necessary, and head it off at the pass.....at the moment, it seems to be working ok. Tomorrow - who knows!? I haven't heard of the McKenzie method either, but I'll bet someone here has. This is a really good place for fibromites to find understanding.
