Dizziness should always be evaluated by a qualified ENT specialist. While most MD primary care doctors and ENT specialists aren't trained to evaluate the neck, this evaluation is strongly recommended to rule out an inner ear problem. If the inner ear checks out, consider getting the upper part of the neck 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) or a high level Maitland or Paris trained physical therapist. Realize that out of 10 practicing physical therapists in the US, only 1 would be expected to have the training needed to adequately treat this area.
