A: Yes. Always get medical treatment immediately following an accident. It can only help your case. Be sure to explain any pain or discomfort to your doctor. Some injury symptoms may not appear immediately following an accident. If you wait to get treatment, insurance companies will argue that your injuries were not caused by the accident, and they may refuse to pay. Report any headaches, fatigue, muscle soreness, nausea, pain, or discomfort that occur within days of the accident to your doctor.
