You should always get checked out by a doctor after getting into any traffic accident, especially a truck accident. Some injuries don’t show symptoms for hours, days, or even weeks. Delayed discovery is especially common with whiplash and brain injuries. Internal injuries and organ damage might not show immediate symptoms either and can be fatal when not treated. If you were involved in a severe truck accident, it’s likely emergency response teams showed up at the scene of the accident. If you weren’t conscious, you likely were transported via ambulance to the nearest emergency room.
