Hi, Lisa.
When it comes to the neck, nerves and neurological symptoms, I think that anything is possible so there is certainly a chance that some of the dizziness is coming from the stenosis. Having said that, C-6, C-7 is not usually going to be linked with dizziness – that would usually come more from C-1-3. Issues with the Atlas and Axis (C-1 and 2) are frequently implicated in dizziness. C-6/7 usually will affect the arm, hand, etc. Any or all of them can account for neck pain and corresponding headache pain. Like I said, however, it is possible that the neck is a trigger for the symptoms you have. I agree with you, however, that it doesn’t really give much explanation for light and sound sensitivity other than the vague notion that the weakening of the physiology of the CNS has left you more predisposed to sensitivity to outside stimuli.
In any event, I don’t see a reason you wouldn’t do the injection therapy unless you had some problem with steriods (allergy, etc.). Surgery – anywhere along the spinal column – is really a last resort in my view. They wanted to cut my back open and I said “not happening.” Took me 9 months of various therapies but the back (this is lumbar region) is doing fine at this point.
Best,
Andy
