Hi there. The vertebral arteries traverse through the inter transverse foramina of the vertebrae in the neck and may b being compressed from the adjoining cervical nerve roots in the neck. the signs and symptoms of ischemia through the vertebral basilar arteries could involve any structure of the brain stem, thalamus and hypothalalmus. Chronic ishemia could affect the blood flow to the cerebellum affecting balance, coordination and gait. Ischemia is also a cause of demyelination. Please consult a neurologist for appropriate intervention. Take care.
