don't know how odd this may sound to you, but have you tried using crystals to help? My friend started going to crystal healing sessions and they worked wonders on her joints and general energy levels. Might not be your thing though.
You probably know most of this already, but just incase, you know cutting down on dairy, wheat and sugar can help? Although of course it's impractical.
If you are interested in the crystals, I can help you out with choosing/getting a few good ones. If not then oh well
not everyone goes for it.
