Hey Sissy, in case you're debating it... after my really bad concussion, I think i waited at least 3 or 4 months or so before I did any kind of running. Then I started back really lightly.

I was still having light "headaches" then almost 24/7. "Concussion head" is what I used to call it, for lack of a better term. If I remember correctly, when I first started jogging again, exercise would actually temporarily make my "concussion head" slightly worse, but then 30 minutes or so after finishing it would actually feel better than before. I have no idea the why's of any of this, but someone on the board mentioned it could have to do with blood pressure and such. As I ran more and more my body seemed to get used to it.

I was reading on another website how the brain is REALLY vulnerable for the first few weeks after a concussion. After reading this, I may wait even longer now.

Whatever you do... start back slowly... and carefully.
