Nats cool,

Sounds like you found a real jerk of a doctor. He says they are not seizures but it appears he did not offer an explanation of what they could be. The intense questioning is also a sign that he is missing the boat. If he does not recognize your PCS symptoms, he should not have been examining you. You need a concussion mTBI specialist.

Have you checked with http://www.headinjury.com/ ?

They may have a recommendation of a concussion specialist.

My best to you.
