Go to ER now: Call an ambulance and do not drive. You need yo get there quick in case you have a brain bleed. Hurry!

Doctor Time: Sounds like you may have had a concussion. These symptoms however warrant a detailed medical exam that is beyond the scope here. To the doctor!

Go to an ER: Go to the nearest er as soon as possible. You need to be evaluated for internal bleeding or other serious injuries.
