I read in another thread that someone who went to a concussion clinic in Buffalo for athletes was told by a physician there that their cognitive deficits were cause by a neck injury.

Could some PCS symtoms be caused by bulging disks or whiplash, etc.?

I know I didn't have neck issues before the accident and an MRI taken of my neck after the accident shows that I now have bulging cervical disks.

Here is an article about research done with this in mind.

The only thing is, it could be minor axonal injury or concussions *in addition to* the whiplash.

I find the idea very interesting. Maybe some of our symptoms could be relieved with some PT or surgery or something...?
