artery disection or cervical spine pathology

I wondered if you could tell me if an artery disection - etither vertebral or carotid might be consistent with an elevated C Reactive Protein (highly specific) of 26.

I was in  an auto accident ( hit from benind by dwi) this past summer and have been left with neck/jaw pain - loss of equillibrium - and disturbed vision.  I've been attributing many of the symptoms to pathology of the cervical spine, however recent blood work came back with the C Reactive Protein elevated to 26, and TPO antibodies elevated to 550.  

The bloodwork was done because of recent onset of very severe 24/7 skull/head pain.  All other symptoms were there prior to the headpain (neck pain, jaw pain, shoulder pain, disequillibrium, problem vision etc.).  The head pain onset was 6 months after the accident and unlike any headache I've had in the past - currently taking round the clock Ibuprophen and sudafed for partial relief.

Any insight you might lend would be wonderful.  I am scheduled to see a neurologist next week and am going to have an MRI Brain w/o contrast prior to that.
