Johnson,

Welcome to NeuroTalk.

Some people develop a severe sensitivity to any form of head jarring after a concussion. This can be a sensitivity to a simple jarring like you experienced parking your car. It is a common symptoms of Multiple Impact Syndrome.

In your case, you may have also suffered whiplash during any of your previous head bumps. The neck is often overlooked after a head bump. Whiplash combined with concussion can cause some odd symptoms.

As crystal said, seeing a neurologist may be a good idea. You also may consider seeing a specialist in Physical Medicine and Rehabilitation, especially if you can get a referral to a PM&R doc who has good knowledge of concussion issues. A PM&R docs are often called a physiatrist.

You may find some information about local mTBI care at http://www.headinjury.com/

You may need a vestibular analysis done to see if vestibular therapy can help.

Keep looking until you find a doctor who listens to you.

My best to you.
