alexg,

Welcome to NeuroTalk.

The head sensitivity you mention is very common. Many of us have learned to reduce these exposures. As FunGames said, this sensitivity can be related to an unresolved upper neck (C-1 and C-2) injury. Most professionals will all but laugh you out of their office is you bring this subject up. Very few will under stand how to treat this subtle upper neck injury.

When riding in a car, you can reduce the intensity of the bump by leaning forward so you back is away from the seat. This allows your back to flex and absorb much of the bump.

A neck specialist like a www.nucca.org or www.atlasorthogonal.com chiropractor can take x-rays that can identify this upper neck instability then treat it. It will take discipline on your part for healing to happen. You will need top be disciplined with your head and neck posture when sleeping and resting.

You may not find improvement. Some of us who have experienced multiple concussions have had this problem for years without much improvement. We just learn to moderate movements and such.

My best to you.
