Hi Az-Di,
I have tried most of the meds and treatments for CRPS over the years,and had the stellate blocks many times without too much trauma ...the meds are all trial and error as we are all different, and I agree that most of us will always need some from of meds to maintain.
What I do on my own, now that PT is off my books for insurance reasons, is adaptive Yoga... and it is helping so much! My body feels relief as does my mind. I also use magnesium supplement for my muscles and cramps mostly,but it does also calm nerves, somewhat. Short walks when I am able also help keep me going. I don't know. We just keep on trying!!
May we all have easing from this pain,

Hana
