Persistent does not mean explained

The passage of time does not identify the cause. A clinician still needs the original crash details, first onset, earlier examination, and the course since then. Bring emergency or urgent-care records and note whether the headaches began immediately, appeared later, or changed character.

Include any period of improvement followed by a return or escalation. MedlinePlus provides general headache information, but a post-traumatic pattern should be evaluated with head, neck, sleep, vision, medication, and neurological details together.

Danger signs still matter weeks later

Call 911 or seek emergency care for a headache that becomes severe or continues to worsen with repeated vomiting, seizure, weakness, numbness, reduced coordination, slurred speech, increasing confusion, unequal pupils, loss of consciousness, or inability to wake. The CDC lists these as concussion danger signs.

A new injury or another head jolt during recovery also changes the medical timeline. Do not drive when headache occurs with vision change, dizziness, slowed reaction time, poor balance, or impaired concentration.

Look for a repeatable pattern

Track headache days, start time, duration, location, and quality. Note whether screens, reading, light, noise, neck movement, posture, exertion, driving, poor sleep, or a particular time of day changes it. Record nausea, dizziness, vision problems, memory difficulty, mood change, neck stiffness, and pain near the base of the skull.

Mayo Clinic includes headache, neck stiffness, and other symptoms in its whiplash overview. List every medicine, dose, and time taken for the headache. Do not stop or change prescribed medication without speaking with the appropriate clinician.

  • Number of headache days and duration
  • Location, quality, and direction of change
  • Visual, cognitive, balance, and neck symptoms
  • Activities and environments that trigger or worsen pain
  • Medication use, sleep, and work limitations

Concussion recovery may need reassessment

Concussion symptoms can include headache, dizziness, fatigue, vision problems, concentration difficulty, mood change, and sleep disturbance. MedlinePlus summarizes the symptom range. If symptoms remain limiting, ask whether the original diagnosis and activity plan should be reviewed and whether another clinician, such as a provider experienced in brain injury, headache, vision, balance, or rehabilitation, is appropriate.

The CDC recovery guidance recommends a gradual return to activity based on symptoms and professional advice. Report a decline rather than continuing the same progression automatically.

Set a concrete review point

Agree on what will be tracked before the next appointment, such as headache days, screen tolerance, walking, driving safety, sleep, or a work task. Use the same measures so change is easier to interpret. Ask which finding supports the current explanation, what alternatives remain, and what would lead to imaging, referral, or a different treatment plan. No provider should guarantee that one procedure will end every post-crash headache.

Bring the updated diary and medication list to each visit. A new neurological sign or meaningful loss of function should prompt earlier contact rather than waiting for the scheduled review.

Headaches continuing weeks after a collision deserve a fresh clinical review, not automatic continuation of the same plan. Keep a clear pattern record, watch for danger signs, and use measurable function to guide follow-up.
