What is post-accident headaches?
Headaches that begin or worsen after a car accident are usually cervicogenic, meaning they originate in the cervical spine rather than in the head itself.
When the upper cervical joints are irritated by the impact, they refer pain into the base of the skull, behind the eyes, and across the temples in a pattern that can mimic a migraine.
Because the source is in the neck, medications that target headache symptoms rarely provide lasting relief. The pain returns until the underlying joint and muscle dysfunction is corrected.
Common symptoms
- Pain that starts at the base of the skull and wraps forward
- Pressure or tightness behind the eyes
- Headaches triggered by neck movement or sustained posture
- Sensitivity to light or sound
- Nausea with severe episodes
- Tenderness at the suboccipital muscles
- Daily or near-daily headache pattern after the accident
How we treat it
Care focuses on the upper cervical spine, where most post-accident headaches originate, using precise and gentle adjustments to restore normal joint motion.
Soft-tissue therapy on the suboccipital muscles, upper trapezius, and temporalis breaks the tension cycle that keeps the headache firing.
We treat the source rather than masking the symptom, so patients typically see the frequency and intensity of headaches drop significantly within a few weeks.
Postural retraining and simple home exercises help keep the headaches from returning once the active care phase is complete.
When to seek care
New or worsening headaches after a collision should never be ignored. Early care resolves most cases quickly and rules out anything more serious.
Remember that pain from an auto accident is often delayed by 24 to 72 hours. Adrenaline can mask the injury at the scene, so even mild symptoms after a collision are worth a same-day evaluation.
