Get Treatment As Soon As Possible
You should always seek treatment as quickly as possible following your injury. While you may want to tough it out, or avoid missing work, your failure to take care of yourself can be interpreted by an insurance company or a jury as indicating your injuries are not as severe as you claim. Do not take that risk, and seek treatment immediately.
In the event of life-threatening injuries, you may be taken from the scene of the incident directly to the emergency room. If you have injuries that are not life threatening but still require immediate treatment, you may want to visit an urgent care facility.
But I Feel Fine!
If your doctor asks for a follow-up appointment, make sure to keep the appointment. If you continue to feel pain or other symptoms, schedule a follow-up yourself. If your doctor refers you to a chiropractor, physical therapist, or another specialist, schedule an appointment as soon as possible to continue your treatment.
