You sound like you are suffering Post Concussion Syndrome symptoms. Based on your immediate symptoms of amnesia, etc. these symptoms are not unusual.

Have you ever been seen by a doctor for these symptoms?

I would suggest a visit to a doctor who understands post concussion. A Physiatrist and Rehab specialist MD would be a good start. I think they are better than most neuros for a head injury like yours.

Write down all of your symptoms with details about when you have them.

You could also look up the local brain injury association for a possible referral.

Either way, you would benefit from doing some research into the resources available to you locally. Some sports medicine doctors have MTBI referrals for you.

You are just starting the search. Be patient, it is sometimes difficult to find the right physician to help with MTBI.
