Front Seat Head Restraint problems of the 2007 Jeep Wrangler

I was rear ended and pushed into another vehicle. I was driving a Jeep four door and my head hit the head rest which is very hard. I have had headaches ever since and the seat belt locked down so tight that my shoulder has hurt ever since, no broken bones, but something is not right. I know for a fact the headrests need to be evaluated on their safety! I have an appointment with the Jeep place for another recall and that is when I am going to discuss the hard headrests again.
