Welcome to Neuro Talk Colin. I am sorry however that CRPS has brought you here. There are alof of people who have this condition. Please don't loose hope. Many should respond to you, and maybe give you some advice.
What I have heard about that our vets have access to the most are Ketamine infusions. There are locations thoughtout the country. This has had some good results. The JAMA a medical journal has had some published results. In my state, Tampa Hospital, is the location that has the Ketamine infusions.
I also hope you have the very best pain specialist in your corner. Maybe if you ask him, he will know of this therapy. I had Ketamine infusions in my spine before my cervial fusion. It worked for me, and gave relieft for a few months at least. I had two, and then was told I needed the spinal fusions.
I really wish you all the best. Too many have to suffer with CRPS, and I really hope that someday a permanent solution can be found. ginnie
