thanks for responding...I think I am going to go to the doctors to see what they say...thanks for your help!!!
Dizziness can definitely be caused by Cervical spine problems, and the fact that it happens when you move your neck a certain way, pretty much confirms it. When you move neck a certain way, a nerve is probably being compressed.
Sorry, I don't know anything about dizziness and sleeping. If you have a family doctor, that would be a good place to start. Since your neck pain correlates with the dizziness, maybe some imaging test would be in order.
