Just chiming in really quickly here because I noticed that you play hockey. I was injured in a somewhat similar fashion. Despite playing in a no checking league, I was hit hard and high during a game and my head went flying into the glass. I don't believe I lost consciousness, but I really banged my head on the glass and ice.

I rode the pcs rollercoaster for many months, probably close to 11. Things finally started to level out after that and I am feeling much better now. Not perfect, but so much better than the sick mess I was for so long! I can tolerate noise, crowds, stores, even the bright lights of a rink now. I couldn't for many, many months. So hang in there and try to take it easy if you can. I think the rest really does help.

Also, 1 year after my injury I was diagnosed with a pretty bad neck injury. I new my neck was injured from the hit, but doctors didn't feel like giving me a cervical mri until 12 months after the damage was done. Not sure if you've had a neck workup yet, but it might be something to consider. Neck injuries can contribute to pcs like symptoms. Good luck in your recovery!
