Taresaj,
Blocks can only do so much, and it seems that you've run that course.
You probably need to be sent to a good Pain Management Psychiatrist, and/ or someone who specializes in RSD. Along with some specialized PTherapy.

You will get more comments and support, as you came to a very good place.
While I"m sorry you needed to come here, I welcome you!
