I believe all the theoretical knowledge and technical components exist to build a nerve imaging machine which would be of extreme importance in numerous diseases and could be used to prevent RSD in virtually all cases. It would be of no or very limited usage for treatment of RSD probably but at least it would spell the end of suffering for millions in the future.

It does seem there should be a way to break the cycle of pain and I believe most of the research is actually going into learning the nature of pain so it can be comtrolled directly. Frankly I'm not convinced this will prove to be the correct tack. Pain may prove too amorphous and too widespread in the brain and body to be readily attacked directly in most instances.

There is likely to be a cure someday and it might be much sooner if they put more research directly toward solving this specific problem.
