Hi Oakland - sorry to hear about your PCS issues. I skate too as well surf, paddleboard, mountain bike - you name it, if it involves being outside, I'm on it. But I've had to put that on hold for a while. A couple of months ago, I fell a bunch during a week of cross country skiing. Never hit my head, but apparently my brain didn't like the jarring from hitting the ground and I have been experiencing PCS symptoms ever since.

To answer your question, my symptoms are pretty static but will spike if I drive for more than 10 minutes. For some reason, I'm really sensitive to the jostling you get riding in a car on urban streets.
