The one thing that I can think of that could help would be high dose fish oil. Specifically Dr. Lewis' protocol.

BHERI | The Omega-3 Protocol for Brain Health

Personally, I saw results right away. I also have this head sensitivity to movements. It does get better with time, but concussions need to be avoided.

Small movements and most bumps to the head are not concussions, BUT they can cause similar symptoms than a concussion from a chemical cascade.

Hope this is helpful!
