What did the Dr say about the MRI report?
It didn't even clarify if there is uncinate spurring or not - says probable?
Maybe another imaging technique would clear that up?
Then the probable hemangioma in the t2 vertebrae - that needs to be clarified also.
I would request those issues are looked at again to see if something is there or not. Then go from that point.
For the pain from the neck into the arm - if those MRI issues are found to be NOT the cause of the pain, it will help if you tell us about your hobbies, any previous injuries in the head/neck area.
If you've ever had whiplash, or do a lot of computer, gaming, sports, musical instruments, your symptoms might point toward Thoracic outlet syndrome.
But more information from you is needed before we go there..
Or if you want to read about it we have a forum for it-
The sticky threads at the upper section will give you a crash course on TOS-
