Dizziness may result from injury to facet joints that are supplied with proprioceptive fibers; when injured, these fibers can cause confused vestibular and visual input to the brain.
Headache is a frequent symptom of cervical strain. Neck structures play a role in the pathophysiology of some headaches, but the clinical patterns have not been defined adequately. Increased muscle hardness (determined by palpation) is significantly increased in patients with chronic tension-type headaches. Facet joints and intervertebral disc damage have been implicated in the pathology of headaches caused by neck injury. No specific pathology on imaging or diagnostic studies has been correlated with cervicogenic headaches.
Late whiplash syndrome includes symptoms such as headache, vertigo, disturbances in concentration and memory, difficulty swallowing, and impaired vision. These cognitive impairments remain poorly understood.
At the time of accident, neck pain may be minimal, with an onset of symptoms occurring during the subsequent 12 to 72 hours.
