Rest up, Shooting Star. You have received very good advice and care. Don't mess around with this. I have a friend from grad school, whose daughter had a concussion from a soccer head butt. It was a long time before she could do everything the way she used to.
Yeah, and I am also against all of those things you mentioned. I am pretty sure I had a mild concussion when I slammed the point of my car door into my forehead. I rested for 1.5 days and stupidly went on a 30 mile ride the day after that. This resulted in headaches and neck pain for months. Take it easy!!!
