I know how you feel, but as Mark says, its impossible to get a concussion from a wind. When it is stormy outside I am more worried, that a road sign or similar will come lose and hit me in the head.

Are you treating your neck? I cant see how theese issues should be brain related (except anxiety) but perhaps you have a upper neck injury? I read somewhere that it is "normal" for whiplash sufferers to get symptoms from eg braking the car quickly - I also get symptoms when doing that, and I think I read in one of your previous posts that you also have this.

I am no expert but perhaps you should look more into upper neck injury than concussion? As Mark has said many times, think posture when relaxing and sleeping, perhaps some PT masage, NSAID and warming your neck. And move around as much as possible in a way that doesnt give you symptoms. Just some suggestions...
