By any chance do you have a MRI written report to share, the spinal forum would be best to post that info.

If this could possibly be related to repetitive motion injury (desk work, overhead, heavy lifting, prior whiplash etc)- you might want to read on our thoracic outlet syndrome forum also.
C spine symptoms can be very similar to TOS symptoms, and possible to have both.
