The most common symptom of whiplash is neck pain, which can range anywhere from mild to pins-and-needles tingling to excruciating. Other symptoms can include neck stiffness or reduced range of motion, neck instability, shoulder and/or upper back pain, or headache. There could also be tingling, weakness, or numbness that radiates into the shoulder and/or down the arm.
While the severity of the car crash usually correlates to the severity of the whiplash injury, there are exceptions. Sometimes a sturdy car does not crunch up and thus shows no significant outside damage, but the forces that were not absorbed by the car exterior were instead transferred through the seat and thus caused worse whiplash. Also, whiplash injuries have been recorded in incidents where the speed at impact was less than 10 miles per hour.
