Any experts out there on cervical dystonia?

I need to find out if whiplash would have caused this condition in my case, since it involves a auto accident 1 1/2 years ago. I suffered from musculoskeletal strains/sprains in the cervical, thoracic and lumbar spine areas, as well as a annular bulge at C5-6. I have gotten worse over time with severe muscle spasms in the spine and aggravation of pre-existing fibromyalgia, on top of other medical problems including degenerative disc disease. I was diagnosed with cervical dystonia yesterday and received marcaine injections and will return in three weeks for more, probably with Botox or Myobloc.
