Welcome!

It sounds like you're going to a chiropractic neurologist (or functional neurologist). I saw one too and also have the sensitivity to bumps, shaking of the head, etc. Unfortunately, it didn't help me much. Some see results, others don't with CN's.

I tried the quick head turns, and after a certain one, I immediately felt like I had another concussion. I know I didn't, but it felt like it for a week or so. I say trust your gut and don't do the quick head turns. Doing them slowly is fine for me. I've found similar results as you. The less quick head turns, bumps in the road, etc., the more I can tolerate. I've had periods where I can even run.

This brain sensitivity I've found does not work with desensitization techniques. I wish it did, but the fact is that it doesn't. With time, it does get better, as long as you don't overdo it with the car rides, bumps, head turns, etc.

Anxiety makes it worse, so it's best that you can get that under control. Some people will say that it's simply anxiety that causes the symptoms. I strongly disagree. The brain being sensitive to movements is the main problem. That's where the anxiety comes from (for most people) Anxiety is a secondary problem, BUT the anxiety can cause more symptoms than the brain being sensitive to the movements.

Let us know if there is anything else that we can help you with!
