Hi. Thanks, however I already got myself into trouble but getting caught up in the long bike ride. I learned the hard way, unfortunately. I did get into a concussion clinic for better care. Wish I had found out about them earlier.

But to get back to my question of, "What Does Extreme Physical Exertion do to a PCS Brain?" I'm trying to figure out what happens at a biological level. I guess my thinking is if I can understand that then I can figure out whether or not I did any long-term damage. I had PCS for 8 months, went on that MTB ride, then my symptoms worse than they were at the beginning.

p.s. Joannetb - It's great you found a specialist that gave you that helpful information. My neurologist didn't cover things like that, unfortunately.
