I am a 12 year old and I know what you are going through. Crazy right. I know it is really hard to be going through this but you are not alone. There are lots of people who get concussions all the time for doing odd things. Unfortunately you have a post- concussion syndrome which takes a little longer to recover from. I have one too and have had mine since December. I have not had once a headache free day. The doctors are trying to help you as best as they can and I think you know that. But they have done everything in their power to try and get you better without much success. Have you tried PT and/or OT?
