I had some microcurrent therapy on my area of CRPS. (toe/foot) It was available at my chiropractor. There were many different frequencies that we experimented with. Unfortunately, this therapy was of no help for me. In fact, it seemed to aggravate the area some (not all) days.

But as everyone knows with CRPS, "your results may vary". Everyone is different and everyone can respond differently to different meds and therapies. There is only one way to find out. Try it.
