Welcome Ipronovost25,
I am sorry to hear about your pain.
Some of your symptoms sound like they could fit in a couple differnt categories but we have had some members on the TOS forum that have had some car accidents and resulting shoulder and neck pain that sounds similar.
Check out and do some reading on the TOS (thoracic outlet syndrome forum). Maybe it can help with some questions for when you see the specialist.
Here is the link. At the top of the forum we have some stickies that have some great information.

Good luck and keep us posted.
