Yes, I was diagnosed with RSD, (aka CRPS, also Sudeck's Atrophy) in 2011. It started with a broken forearm, high speed accident. Bone didn't heal, non-union, fingers became huge blue sausages while in cast, then tendons in hand permanently contracted to claw shape, shoulder became frozen with adhesive capsuleitis, and finally RSD spread to left shoulder, arm and hand as well.
Astonishing, life ending, level 10 pain, 24/7 for six years, cycled through vast number of drugs/treatments which all failed.
Finally it stopped completely when I started taking daily high dosage full spectrum CBD oil to treat another condition.
I still take the daily CBD oil. The RSD symptoms and pain never returned.
It took about three months after starting the CBD oil for the pain to drop 50%, and a full year before pain and other symptoms were fully gone.
The contracted tendons and claw hand of course were permanent.
