This is more commonly due to a disc problem in the neck..the cervical spine.
It requires an MRI to see this.
This will confirm if there is nerve compression..
And x ray can not show this accurately.
The artery would not use this unless it cause a stroke.
The stroke might have some of the same symptoms but not the neck pain typically.
So what I would do is this
Have your doctor order an ultrasound of the neck arteries..it will show if they are clear.
See a physical medicine and rehabilitation doctor for the neck..he/she can see if there really is nerve damage or not in the office with a conduction study..and give you the correct manual therapies to fix this and avoid possible surgery in the future.
