I just wanted to say that I agree with some of the things said here! For me, when I was recovering from my concussion, I could spend HOURS and HOURS watching TV or on the computer, or staying up late and I would get no relapse in symptoms. But if I ran the car out to a friend's house I would get overstimulated.

I think being in the car was just a whole other level of processing my brain was dealing with. It eventually went away. It's just weird that spending hours reading or on the computer was not stimulating....but doing errands was. I feel like some doctor really needs to take the reins on this and start with interviewing people with PCS. Hell, I would do it if that paid me to
