My c4, c5, and c6 is protruding can this cause dizziness and imbalance?

No: Protruding discs do not cause this. Blocked arteries up your neck or medications or brain problems including tumors can do this - best see your family md who may send you to a neurologist.

No dizziness : Cervical problems will not cause dizziness. Imbalance can be caused by cervical myelopathy, a severe compression of the spinal cord. However, your both of your described symptoms could be caused by vertigo. If your cervical discs do not cause severe central canal stenosis, i would not attribute your symptoms to your cervical spine.
