I've had it done and had some relief. I've also had a very scare experience of mirroring in my "good" hand caused by an IV needle in the same spot two weeks in a row.

Accupressure might be safer.

You just never really know with RSD... You're also unlikely to find someone with RSD experience. If you try it and have a flare--especially in a new region--treat the problem area quickly and aggressively like you wood with any new problem area. For example, I dropped something on my foot yesterday. A few hours later and my foot was ice cold and RSD pain was creeping up... I through on a Lidoderm patch and took extra breakthrough meds. The pain is reduced to a level that seems appropriate to the injury now, but the temperature regulation is still off... It took me about a week to get my hand back to normal after my IV scare.
