Drs can't find a med or some other thing to release those spasms and lock ups at all??
This is off the topic of the skin part of your question, but have you ever read about with EFT ? --Emotional Freedom Techniques--

It's basically tapping on certain points in a rhythm and a sequence - another person can do the tapping for you-
It include some phrases but I didn't even use them when I used this for my RSI in 99.
I know it sounds really strange but RSD is pretty strange too right??

It supposedly helps to reprogram the body systems.
No side effects from trying it, unless the tapping is painful for you.
In a section on the site there is info on tapping by proxy- or some of the therapists can work it over the phone.
Or maybe i saw that in the emailed newsletter I get from them.
