One of my co-workers teaches hypnosis as a sideline. He goes all over the world teaching hypnotists. I really don't know why he works where I work, as he makes a lot of money being a hypnotist. Even more teaching other hypnotists. For an example, he does a two hour stop smoking hypnosis session - it is $695. For TWO one-hour sessions! YIKES! He says it will only work if the person really wants to quit, so he is really careful to pre-screen people ahead of time, and only takes people he thinks are ready to quit anyway. That keeps his success rate up.
I asked him about hypnosis for RSD. He said it sometimes works for people in pain, but you would have to go to someone who really specialized in pain hypnosis, and there are very few hypnotists who are really good at that. He said they would be really expensive - probably $500 or more an hour


and insurance rarely covers hypnosis. He suggested meditation instead, which I already do. He also suggested accupuncture. I have read some horror stories about accupuncture and RSD though, so I am to chicken to try that. His conclusion is that someone with the severe pain of RSD would probably not get any real relief from hypnosis.
Just throwing this out there for what it is worth. Perhaps your Dr. knows someone in particular that might help you. I doubt it could hurt to try it....
