Thank you so much for such a detailed response, Mark--I think you're understanding exactly where I'm coming from, which isn't that common in relation to PCS it seems.

You're totally right about running being jarring--more times than not it leaves me in a state of disorientation. I had just never thought about the shock going all the way to my head! It really does make a lot of sense.

Crew is definitely an option. My school has a really strong program, and a lot of my friends are actually on the team. I had been considering it as an alternative even before you mentioned it, but now it's making the switch from hockey even more logical.

Anyway, onto those symptoms...

List of persisting symptoms:

• sensitivty to light
• insomnia
• chronic headaches/migraines (currently taking topamax w/ no significant relief)
• depressive feelings

List of the less bothersome, though still worrisome symptoms:

• dizziness when rising too quickly
• tinnitus, comes and goes
• disorientation/feeling like I'm in a dream when overstimulated

Those are the ones I can think of. I tried to keep it as simple as possible, but I can add details as needed!
