After you have been involved in an accident, see a doctor as soon as possible. Besides the importance to your well-being, it also means that your injuries are documented from the start. It will be crucial evidence, should ICBC argue that you weren’t injured in the accident because you never sought early medical treatment.
If you can’t see your regular doctor within 24 hours of the accident, go to a walk-in clinic or a hospital emergency. Don’t delay seeking medical treatment, even if you are hoping things will get better on their own. Not seeking immediate treatment can be used against you later.
