Hello dominicana,

Did you find our RSD forum already?

You mentioned injury to your head, neck and shoulder also... Have you read any information about Thoracic outlet syndrome {TOS}?
you might want to read a bit about that if you aren't sure of your RSD diagnosis.

This useful sticky has info on both conditions and various treatments -
