Mark, thank you for response!
bmwbzz, hang in there. I think, you have a very good chance of recovery (if it was your first concussion). Just be careful - don't get a second concussion! Every time it takes much longer to recover up to a point when your symptoms just don't go away.
I've had ~6-7 concussion and some number of sub-concussive impact. All happened purely by accident and/or out of my own stupidity. So, now almost anything now(minor impacts, anything that makes my heart rate go up even a common cold) causes a setback. However, this is a first time when it takes so long to recover considering that I managed to go the whole year symptom-free.
So, you hang in there and it will get better. This is scary and frustrating, but it gets better. Wishing you quick and full recovery!
