Hi Greco and Welcome to NeuroTalk
I personally don't know enough about your type of injury to be able to answer your questions myself.
The people on the Spinal Disorders forum can probably offer the type of information you are looking for, and we also have a forum for Thoracic Outlet Syndrome and the people on that forum might also be able to help you.
Here are links to those forums-
Spinal Disorders Forum
Thoracic Outlet Syndrome forum
I hope that helps, and Welcome to NeuroTalk
