The sooner, the better, stating that we have suffered a traffic accident and the injuries that we have (you must check before leaving the hospital that all the injuries are stated on the report).
It is important that you indicate everything that hurts (knees, elbows, cervical or lumbar region, etc…). It might not seem important at the time, but further along this could turn into an injury.
If you have been discharged from hospital, and more pain appears, you must attend the hospital once again and state once again that you suffered a traffic accident and you have a new injury, but do not attend the hospital at all times – ONLY WHEN IT IS ABSOLUTELY NECESSARY – (The emergency service must not be obstructed for minor issues) but if you consider that the pain that you are suffering is important, do attend the doctor as many times that you feel necessary.
