Having worked in a motor vehicle claims department for a large insurance company, (straight out of school). My approach to a motor vehicle accident is to avoid them at all costs.

Whiplash is caused by a sudden movement of the neck, forwards, backwards or sideways. Injuries to the tendons, ligaments and muscles occur.
Usually the neck has been pushed past its normal limits.
Symptoms include -:
Treatment
Often it is necessary to see a physiotherapist. The problem can be that the small muscles of the neck have received trauma and switched off.
The larger muscles take over, however the problem is these large muscles were not designed to hold the neck up.

Your chiropractor may record the details and recommend you seek a motor vehicle accident lawyer
What you may be able to claim-:
