Thanks for your responses and encouragement. So far I have seen only one case where flying has caused weeks of setback, in my case it was months (6+ so far). If any of you fall in this category please let me know.

update

I went to a new neuro. He is not a concussion expert but a migraine expert. He said that it is very possible, based on my symptoms, that I have "vestibular migraine" which is a type of migraine that causes dizziness (and not necessarily headaches).

He recommended I try one of the following:

Depakote
Topomax
Propranolol
Tricylic

I am running this by my other doc. Any thoughts? I looked at a vestibular migraine forum and they have very similar symptoms. They get dizzy from random movements. They have brain fog, fatigue, migraines, but mostly dizziness/vertigo.

I also came across the following syndrome which usually happens after travel
