I'm not sure if either would qualify as a concussion, but I'm glad that they didn't increase your symptoms.

You said your biggest trouble, other than fatigue have to do with balance/coordination. Have you tried vestibular therapy?

I'm 25, and have had 3 concussion, the first two not nearly as bad as this one. I started vestibular therapy 2 months ago and it has really helped me. I no longer have trouble moving around, (except for backwards and in the dark. Both of which are being targeted in therapy). When I started, I couldn't even stand up with my eyes closed without support from two therapists or I would fall down. Now I can do it for a minute, on a squishy, by myself. It's really been a life savor for that part of my symptoms.

As for fatigue and emotions... I'm still stuck there.
