I understand your plight. I have had RSD since 84'. What has helped me the most is name brand Klonopin, which stops the body from seizing. Yes, a type of seizures.

I have medical links on why the use of Klonopin, but I do not know how to find these articles someone gave me the link too.

With the WHO renaming this disease, the diagnosis was also changed to change the treatment plans too. So its an uphill battle now with the doctors.
Stanton Hicks has taken over the Ohio and surrounding areas with wrong treatments.

Either way, many of us old time RSD people manage to get the Klonopin we need.
It get the sympathetic nervous system out of over drive and gets the acetocholine to flow properly down the mylan sheath. RSD is the sympathetic system stuck in over drive. Or substitute CRPS is.... whatever they want to call it.

With the use of the Sphnoid block as needed and the Klonopin I am pain free.

I also use homeopathy. There are some basic remedies that work for RSD.
Arsinicum is great for pain. Hypericum for nerves and nerve pain. Ledum for any puncture.
I hope this helps If you know what you have and can explain it to an MD they may be more inclined to prescribe what you need rather than the current trends.
