You're probably fine: An ER Doc decides you need a head scan if any of the following is true: 1. did you lose consciousness? 2. Do you have amnesia for any part of event? 3. Do you have an abnormal neurologic exam? 4. Are you intoxicated? If the answer is no to all 4, studies have shown, the chances for life threatening brain injury are extremely low. Severe headache with vomiting? Then they'll probably scan anyway.
