Ugh, I hate concussions. You spend the first day thinking, "this ain't so bad" and then that sea sick feeling hits you on day 2. Hopefully yours isn't too bad. I had two bad ones both times being rear ended in my car. My horse one wasn't bad at all. My car ones lasted a good 4 or 5 days. If you don't feel queasy the next few days, yours was probably minor and you'll be good to go in a week. Otherwise, just give it a little more time. Welcome to the concussion club!
