My thought would be to find an Anesteologist/PM Dr. They do pretty good at diagnosing RSD and treating it.

I think many of us have went through what you are going through. Drs. donot want to acknowledge RSD due to the long term treatment of it and no cure.

I never had any luck with Neurologist. I saw 4 of them they were jokes. If it doesn't show on their test then most of the time they donot acknowledge it.
I went through that with my TOS and RSD both.

I would try and get some blocks to see if that might put it into remission.

You will get a lot of good help here. Also read up on RSD sites and learn as much as you can about it. Dr. Hooshmand has a good puzzle on a website. Just type in his name.

With RSD the more you learn, the better you can find that right Dr. to help you.

Stick around.
