I had brain/cervical spine MRI normal. Still have problem with my neck causing jump sensations inside head making me fall over to the right?

Not likely from neck. With a normal MRI of your neck, as well as the symptoms that you are describing, I do not think you are having a problem from your neck. It's possible you are describing some seizure activity. I would seek an evaluation by your primary care physician and possibly a neurologist.
Trigger points. You may have trigger points in the muscles of the neck and upper back and referred pain from this points. You may try physical therapy. Consider trigger points injections.
