Hi Cheryl,
Welcome to the RSD/CRPS forum!! I found the following link to Dr. Hooshmand's site linking MS and RSD. If you scroll down 2/3 of the way, you should find it. The first part is very beneficial with a lot of good medicinal information. I am glad you are getting some good relief from the pain with the blocks. Best wishes to you!
