@larryk1 Balance can be affected by so many things like vision, hearing, inner ear problems, and blood pressure. That is something that a medical professional should evaluate. If we were only speaking about cervical spine related balance causes, one of them would be cervical spine alignment. Since you had recent spine surgery, I don't know what was addressed or if you have a normal spine alignment and curvature. Muscle spasms can move the vertebrae by twisting or tilting them. If C1 & C2 are twisted, it can cause vertigo because it can affect the blood supply to the brain because of arteries that run through the vertebra that get stretched because of the twist. There can be muscular headaches because of spine problems. Balance and walking can also be affected by cervical spinal cord compression. I had that happen with an uneven gait because of cord compression at C5/C6, and I had vertigo because of movement of C1 & C2 with muscle spasms. The nerve roots are very specific if they are compressed and affect a specific body part that is serviced by that nerve. The nerve roots for legs are in the lumbar spine, but if there is some impingement of the spinal cord upstream that is sending signals to the legs, it can be affected from higher up in the pathway.

A physical therapist can help a lot with evaluating balance issues. Can you share more specific information about which nerves you believe to be affected? Are you able to work with a physical therapist (with approval of your surgeon)?

Which nerve roots are potentially impinged on your MRI?
