What causes whiplash?

There are two theories: 
i.          Quick movements stretch the neck muscles and tear ligaments
             and tendons around the spinal cord.
ii.         Fluid pressure builds up as a result of the quick movement,
             leading to huge pressures being placed on nerves in the
             spine.

Restriction of neck movements and pain radiating to the shoulders, arms and head

What is the treatment of whiplash?
