Well, seeing that hit and run is a felony, I suggest you give as much detail to the insurance and cops as you can. Then rest assured that if this guy is caught he'll spend some considerable time in the clink.

Go see a good spine doc and physical therapist - in fact, INSIST on physical therapy at all costs. Yes, it can be time consuming, but you'll also give your entire body a tune-up (not just the back).
