I am 17 years old and live in Austin, Texas. My story starts last April 25, 2012 when I received my 5th concussion playing football. All 5 of these concussions happened over 3 years and were very minor, I never lost consciousness and gave each one time to heal. That last one on April 25, however, gave me a headache that lasted for a year.

That headache has just recently gone away, praise the Lord, but it has been replaced by a far worse symptom. After that last concussion from football I gave up football but still stuck with baseball, which was going fine until I got hit lightly on the head with an underhand toss. This normally should not have caused any harm, but because of my acquired vulnerability from previous concussions I believe it gave me another concussion.

That hit happened mid February of this year, about 10 months after my previous concussion from football. Since I got hit with that baseball I have not been able to run or do anything active, because if I do I feel like my brain shakes around in my head.

This sensitivity has gotten so bad I can't ride in cars because of the bumps in the road, can't go out with friends, and can hardly walk because the vibrations are sent up to my head and it feels like I can feel my brain shake.

If I lightly bump my head or have it shake one day, I will feel very bad for about 3 days, headaches, drowsnines, all that, but I will feel pretty good again after 3 or four days of rest.

It is also weird because this shaking of my brain I feel usually happens on the top part of my head, where I have never received a concussion or been hit with anything, all of my concussion have been on the front of my head.

It does not seem logical that I could suddenly go from be able to do so much to not being able to run from a light hit from a baseball. Please let me know if you have any insight as to what is causing this and what I can do to help it heal. Could it have anything to do with the cerebrospinal fluid in my head?

My life has been completely put on hold and I am desperately looking for help and will do anything to get better. I have given up contact sports altogether and am currently completely resting myself. I just want to have my life back and be able to do the simple things in life-drive places, go out with friends, and even play golf. Please let me know if you share a similar situation or have any advice or help. Thanks so much and best of luck with your own PCS situation.
