While parking my car i got distracted and hit the concrete stopper at 10mph and rolled up on it a bit. i was jerked forward by it but was not snapped back by the belt and i didnt hit my head. could i have a concussion or whiplash?

Whiplash: You may have a delayed reaction to this whiplash type injury. Your neck did snap forward and may develop stiffness and pain on motion. Should symptoms appear, apply alternating cold and warm compresses, wear a soft neck collar as needed,and take anti-inflammatory medication like ibuprofen or naproxen,if you can. You may need muscle relaxants which is a prescription item requiring a visit to r MD.
