Headaches After a Car Accident: Assessment and Warning Signs
Patient information from Acute Chiropractic Yakima
July 27, 2026
Auto Injury
Can a headache start after a collision?
Yes. Headache after a collision can relate to several injuries or conditions, including concussion or neck injury. A new headache should not automatically be labeled migraine or attributed to a spinal misalignment. Medical assessment helps determine the cause and appropriate care.
When is it an emergency?
Get emergency help for a sudden severe headache, repeated vomiting, confusion, loss of consciousness, weakness, speech or vision changes, or worsening symptoms after head trauma. Do not wait for a routine appointment to see whether these symptoms resolve.
What can I discuss at a non-emergency visit?
Describe symptom timing, location, triggers, sleep changes, and any dizziness or sensitivity to light. Bring previous medical assessments and a medication list. Some neck-related headaches may be considered for manual care, but benefits vary; chiropractic treatment is not a proven cure for post-traumatic migraine.
Should I stop headache medication?
Do not stop or change prescribed treatment based on this article. Ask the prescriber about medicines, side effects, and other options. If headaches persist or change, arrange reassessment rather than assuming more adjustments are the answer.
