Hi Princessmorticia, welcome.
Most of the posts in this thread are quite old, and most of the posters only stuck around for a short while.
I searched for "spinal accessory nerve" in the archives, and found many posts/threads—all over the place—but mostly in the
Thoracic Outlet Syndrome forum.
You might try asking in that forum, and/or do the same search in the archives (
Search function along the top bar of any forum page) for other discussions relating to this.
Wishing you the best; I don't understand how so many are being injured by surgeons in this way.
