@rkoepke It was just working with my physical therapist to resolve the vertigo. It was worse before I had my cervical fusion surgery because I was getting a lot of muscle spasms. My PT was doing myofascial release and also using a Dolphin Neurostimuator to interrupt pain signals. After surgery and my recovery, my neck spasms calmed down a lot. I can still get some slight rotation, but I realize it when I get a headache, and I do the stretching I need to get it realigned, and there has not been a vertigo episode since my surgery. If your vertebrae are getting twisted and stay that way, it's a problem. I didn't have a surgical fix for blood flow in vertebral arteries, it was just working on muscles to realign the spine properly.

I do know that some of propiception for balance comes from vision. I did some eye exercises following a diagram on the wall for this as part of my spine neck rehab. I think balance isn't just one nerve; it's a lot of nerves and muscle feedback and even hearing that is involved with balance.
