Can you post your MRI report?
What levels of c spine shows a change and how much, usually all it will say is mild, moderate etc.. c1,2 etc?
And list your symptoms?
Whiplash, from my reading about it, can often take months to show symptoms. Maybe it is due to a myofascial injury/response & the changes from that.

There are many highly skilled chiropractors that can & do treat even if the spine has some major issues, or they may just avoid those areas if it is a concern.. Skill & training & experience is what to look for..
