Oh yes, that is a triple whammy for sure..
The RSD /CRPS forum has some alternative therapies things being mentioned , it sounds like that is may be the worst thing now? Sometimes surgery sets it off and spreading.

a few that I recall,
HBOT
tDCS
ketamine
there are also pain med pumps and SCS that have helped some members.

They might have more rx medications being mentioned there , or rx combos that have helped some of them.
