For medical and legal reasons, you should get any signs of an injury checked out as soon as you can. It’s important to get checked out by a doctor after an accident because what seems like minor injuries could be symptoms of something more serious. In addition, it’s important to have a medical record of any injuries you or anyone else in your vehicle sustains during an accident. The sooner you start that medical record, the better. Otherwise, it may be hard to prove that the injuries were actually caused by the accident.
