After a car accident, you may feel a sense of shock or distress. Dealing with logistics like insurance and car repairs may even cause you to put off seeking medical treatment, especially if the accident didn’t cause obvious injuries. Like any trauma, a car accident causes your adrenaline levels to spike. This hormone prepares your body for action in high-stress situations and has a numbing effect on pain. After the threat is gone, you may begin to feel soreness and discomfort that you hadn’t felt immediately after the accident.
