I think its fantastic that your RSD symptoms are limited in area though I realize the pain is overwhelming regardless of the area one is afflicted.
I've been coping w/RSD for 15 years-its everywhere
I find massage very therapuetic but can't say it heals.
I'm currently undergoing cold laser therapy and have had great success so far but we did have to make adjustments to find what worked best and in that process took a couple of temporary steps backward but then many steps forward in benefit and relief. Worth looking into.

Besides a great family support system & my faith-all invaluable, I have a service dog. He helps me with stability and mobility and the management of my pain/blood pressure. Keeps me going which in turns improves my function and reduces my pain level. Check out options if you feel you need this support & it works for your lifestyle.

Good luck.
