If you have dizziness due to this nerve or problems with this level, get it evaluated by your doctor. Dizziness should always be evaluated by a qualified ENT specialist. Again, most MD primary care doctors and ear specialists aren't trained to evaluate the neck, but this evaluation is strongly recommended to rule out an inner problem. If the inner ear checks out, consider getting this level mobilized (direct pressure to treat the stiffness in the joints) by a qualified physical therapist (special training required). Find a level 3 Canadian Manual therapist (there are many in the states).
