How about this being related to a neck injury? Any head bump has an impact on the neck.

On a related note Mark: You mentioned to one of the members to check their neck, because they hit the front of their head and that they my have had a whiplash. What does check your neck mean? MRI?

At the Physio office, they tried to generate my symptoms. Rapid eye movements did not do it. However her turning my neck from side to side got me real bad.

So I have been wanting to investigate that. After all problems in the neck can have an effect on dizziness and headache (and of course neck soreness) as I have. Not sure they have an impact on vision but some people argue it does...
