Thanks as always Mark. I am in DC, and I have seen many doctors over the years. It is just that my work expect me to get disability letters from the doctors that have been seeing me on a regular basis.
I agree with your opinion related to him and what he stated.
Since my main problem keeping me from work is visual, my neuro-ophtalmologist's letter will be crucial. Hopefully he will write it.

Maybe they will give it to me, after some drama. But I wonder, if every year I will be evaluated by an outside doctor chosen by work, how would that even work? You cannot measure nausea, dizziness, sensitivity to light and convergence, tracking,...

I am just afraid to have to deal with this stress for the rest of my life.
