so i crashed my xx. I slid into a bank and i went over the handlebars. I remember sliding into the bank and thinking oh shit. i also remember going off the four wheeler and landing. i remember getting back up and flipping it back from how it had tipped onto its side. i felt weird after i got up but i think i was just frightened and my adrenaline was going. i then had to jog 3 miles back to my house to get my truck and go get my XX. My dad said i hadnt been gone very long either. maybe 20 minutes. I feel a little strange but i felt the same way after i crashed another time but i am 100% sure i didnt hit my head then. after writing this it seems like i do not have a concussion because of all the details and my short term memory is fine. and my helmet looks fine. i think im just a little shaken. but guys who have had a concussion, are there any symptoms that i should be looking for?
