A motor vehicle accident (MVA) can cause injury from the impact or from being thrown around inside the car. You may have a bruise on your abdomen, chest, or neck from the seatbelt. You may also have pain in your face, neck, or back. You may have pain in your knee, hip, or thigh if your body hits the dash or the steering wheel. Muscle pain is commonly worse 1 to 2 days after an MVA.
