I would imagine orthopedic but maybe other members would have a better idea. Have you checked spinal forum for cervical spondylosis?

There is something called cervical vertigo. I'm not sure if your dizzy feeling is like vertigo. I only know about it because I have vertigo post concussions and I remembered seeing it on a vestibular website.

p.s. as you're already seeing a Neurologist, I'd wait for the results of tests to come back and see what he/she has to say.
