Hi Cyn,
Welcome to the NeuroTalk Support Groups!

You may have found it already but here is the link for

RSD and CRPS Forum

Arthritis Forum

Just a thought...
it's not the same condition but considering the type of pain you have, you might actually find some helpful tips for sleeping in the Useful Links section of the TOS Forum

I'm sorry to read about your pain, but I hope you find support and information here to help you deal with that.
