Hi Larriva
Welcome to NT. I hope you find some useful information from past members to help manage the RSD/CRPS.
I don't have RSD but deal with a number of other conditions involving pain so you have my empathy.
In regards to treatment options maybe if you could outline briefly what you've already tried (in terms of medications and/or therapy), it would help others to make suggestions.
Also I don't know how you feel about participating in research studies or trialing the off-label use of (an FDA approved) medication. In may 2016 Stanford University was enrolling patients in a study for using Low Dose Naltrexone (LDN) for the treatment of pain in CRPS. Here's a link to the study info:

All the best for finding some relief.
