Penguin;
A few things you left out. Did you have an injury? What started the onset of the RSD that you assume you have? Tell us more about your C 5-6 injury?
Your healthcare doesn't really matter much, although some of us may be able to advise you.
So, what's up? What's the biggest problem?
Diagnoses of RSD is tuff. Have you had it diagnosed?
It's a clinical diagnoses, i.e. rule everything else out.
So did they do that?
I hope so../ I hope not!
You don't "WANT" This monster!

However, if you do have it, GET TO AN RSD NEUROLOGIST ASAP!
THat's your ONLY Chance, for a cure!
DO IT NOW!
Start on Monday! Have appointments set up with a good neurologist set up by the end of next week! Don't take a NO!

My name's Pete, and you can PM me, anytime.
First things first, you need a Diagnoses!
Then, some preventative care!
(Which, many people here will help with, because I went 7 years with no diagnoses).
I've had Rsd, for 26 years.

I wish you well, I wish you all the best!

Pete
