Why do I have headaches after my car accident?
Post-accident headaches are most often cervicogenic, meaning they originate in the upper neck. The crash strains the joints, ligaments, and small muscles at the base of the skull (C1-C3), and pain refers up into the head. Less commonly, headaches signal a mild traumatic brain injury (concussion) or post-concussion syndrome, which is why a proper evaluation matters in the first week.
