When you're involved in an auto accident, you should seek immediate medical attention first and foremost for the sake of your health. Even if you feel like you aren't hurt and are "normal" after an accident, you should still seek medical treatment because pain and symptoms often show up a few days or weeks after an accident. Secondly, it's also necessary to document your injuries in order to receive full and fair compensation for your damages. Failure to see a doctor timely after an accident may harm your claim. Insurance companies will argue that you really aren't hurt from the accident if you didn't seek prompt medical care.
