Who This Blog Is For: You went through a head or neck injury — a car accident on the Glenn Highway, a fall on an icy trail in the Chugach, a collision on the slopes at Alyeska, or a hard hit that came with life at JBER — and you got checked out. Things seemed okay. You gave it time, the way everyone told you to. Then, weeks later, the room started spinning. If you have been living with vertigo after a head injury and cannot make sense of why the dizziness showed up so long after the original injury, or why it keeps returning no matter what you try, this blog is written for you. It speaks to people across Anchorage, Eagle River, and Wasilla who followed every reasonable step after their injury and still cannot get their balance back.
How many times have you replayed the timeline, trying to convince yourself the injury and the dizziness are actually connected? How many appointments have ended with a shrug and a prescription, without anyone explaining why the vertigo didn’t start until weeks after the accident? How many mornings have you woken up and waited — before you even sat up — to find out what kind of day it was going to be?
The delay between a head or neck injury and the first vertigo episode is one of the most confusing and most important parts of this story. It is also the part that causes the structural connection to get missed entirely. If no one has connected those dots for you yet, this blog is a place to start.
Key Insights
- Vertigo after a head or neck injury does not always begin immediately — the delay of days, weeks, or even months is a recognized pattern that causes the injury connection to be overlooked
- The recognized causes of post-traumatic vertigo — including BPPV and labyrinthine concussion — are what a physician evaluates; a structural disruption at the upper cervical spine is the commonly overlooked contributor
- Even without a direct blow to the head, the deceleration force of whiplash is sufficient to dislodge inner ear crystals and displace the atlas vertebra
- Addressing only the inner ear component while leaving an upper cervical misalignment unresolved may be part of why vertigo keeps returning after repositioning maneuvers
Why Does Vertigo After a Head Injury Show Up Weeks Later?
Quick Answer: Dizziness or vertigo after a head or neck injury may become noticeable days or weeks later, persist after other symptoms improve, or recur with activity and head movement. Possible causes include post-concussion vestibular dysfunction, benign paroxysmal positional vertigo (BPPV), inner-ear injury, migraine, medication effects, visual-vestibular problems, and—in some cases—neck-related dizziness. A proper assessment is important because these causes can look similar but require different treatment.
Many people expect dizziness to begin immediately after an accident, fall, or blow to the head. Sometimes it does. But symptoms may be overlooked early on because headache, pain, fatigue, sleep problems, or stress are more obvious. Dizziness can also become clearer as you return to work, exercise, driving, screen use, busy environments, or frequent head movement.
After a concussion, the brain may experience temporary changes in signaling, energy use, blood flow, and sensory processing. These changes can affect balance, eye movements, concentration, and tolerance for motion or visual stimulation over days to weeks. Dizziness and balance difficulties are recognized concussion symptoms.
One common post-traumatic cause is BPPV, in which tiny particles in the inner ear trigger brief spinning sensations with specific movements, such as rolling over in bed, looking up, bending down, or getting up quickly. Head trauma can trigger BPPV.
Neck pain and restricted movement can also contribute to dizziness after whiplash or trauma, but neck-related dizziness should be assessed carefully after other vestibular and neurological causes have been considered.
Important: Seek urgent medical evaluation for worsening headache, repeated vomiting, confusion, unusual drowsiness, seizure, weakness or numbness, speech problems, double vision, or worsening balance after a head injury.
What Actually Causes Vertigo After a Head or Neck Injury?
When a clinician evaluates vertigo after a head or neck injury, the goal is to identify the specific condition contributing to the symptoms. Post-traumatic dizziness can have more than one cause, so a careful history, physical examination, and vestibular assessment are important.
One common and treatable cause is benign paroxysmal positional vertigo (BPPV). Head trauma can dislodge tiny calcium-carbonate particles, called otoconia, within the inner ear. When the head moves into certain positions, these particles can send an inaccurate motion signal to the brain and cause a brief spinning sensation.
Typical triggers include rolling over in bed, lying down or getting up, looking upward, or bending forward. BPPV can often be treated with canalith-repositioning maneuvers, such as the Epley maneuver when the posterior semicircular canal is involved.
Clinicians may also consider other causes, including concussion-related vestibular dysfunction, labyrinthine concussion or other inner-ear injury, vestibular migraine, visual-vestibular dysfunction, medication effects, and less commonly central neurological causes. These conditions can overlap, which is why symptoms alone cannot determine the diagnosis.
Neck pain, stiffness, restricted movement, and altered position-sense input from the cervical spine may also contribute to dizziness after whiplash or trauma. This is often called cervicogenic dizziness. However, it should be considered only after vestibular, neurological, vascular, and other causes have been appropriately assessed, because there is no single definitive test for it.
Why Whiplash Alone — Without Hitting Your Head — Can Still Cause Vertigo
This is the part that surprises people most, and it matters particularly for anyone in Anchorage who has been through a rear-end collision on an icy stretch of the Seward Highway, a sudden stop on Minnesota Drive, or a whiplash-type fall on a ski run at Alyeska or a trail in Chugach State Park.
You do not have to hit your head to experience post-traumatic vertigo. The deceleration force of whiplash — the rapid back-and-forth motion the head and neck undergo during a collision or fall — is sufficient on its own to dislodge otoconia, the inner ear crystals whose displacement causes BPPV. It is also sufficient to shift the atlas out of its normal position at the craniocervical junction.
This is why patients who were told their injury “wasn’t that bad” — no loss of consciousness, no visible head trauma, no dramatic mechanism — can still develop persistent vertigo weeks later. The force doesn’t need to be dramatic. It needs to be applied to a vulnerable region with enough speed and direction to disrupt what’s held in precise anatomical balance. The upper cervical spine is exactly that kind of region.
Many people who come to Rumsey Spinal Care with vertigo after a head injury initially minimize the significance of the original incident. A fender-bender. A slip on ice. A fall that didn’t seem serious enough to warrant ongoing symptoms. The evaluation, not the story of the injury, is what tells us what is actually present.
Why Vertigo Can Keep Coming Back After the Epley Maneuver
The Epley maneuver is an effective, well-supported approach to BPPV. If your physician or physical therapist has guided you through it and it provides relief, that is a meaningful and appropriate response to the inner ear component of your vertigo. There is no reason to stop.
What the Epley addresses is the position of dislodged crystals in the inner ear. What it does not address is whether the mechanical environment that made those crystals vulnerable to displacement — and keeps making them vulnerable to re-displacement — is still present.
When an atlas misalignment is also part of the picture, the structural stress it creates at the craniocervical junction can continue to affect how steadily the vestibular system functions between episodes. The inner ear crystals get repositioned, symptoms settle, and then the cycle starts again. Not because the maneuver failed, but because the structural contributor was never part of the evaluation.
Upper cervical care is not a substitute for vestibular rehabilitation or repositioning maneuvers. For many people dealing with post-traumatic vertigo relief, the two work best alongside each other — one addressing the inner ear component, the other addressing the structural environment the inner ear is operating within. Recognizing that both pieces may need attention is often what changes the pattern from managed to resolved.
What a NUCCA Evaluation Looks for That Standard Post-Injury Exams Don’t
At Rumsey Spinal Care, Dr. Anthony Rumsey uses the NUCCA protocol — a precise, imaging-guided approach to upper cervical care that measures the exact position of the atlas relative to the skull and the vertebrae below it. Dr. Rumsey is Alaska’s only Certified NUCCA practitioner, a distinction that reflects both the depth of training the certification requires and the scarcity of this level of upper cervical specialization anywhere in the state.
A NUCCA evaluation begins with a detailed conversation about your injury history, your vertigo pattern, and what you have already tried. For patients who experienced a collision, fall, or sports impact — whether recently or years ago — that history shapes what the evaluation is looking for. The imaging that follows gives Dr. Rumsey precise measurements of atlas position that a standard emergency room X-ray or general chiropractic screening is not calibrated to detect.
The correction that follows a NUCCA evaluation is gentle and specific. The goal is to restore the atlas to its optimal position so the craniocervical junction can function with less mechanical stress and the vestibular system can operate with steadier, more consistent input.
For anyone dealing with vertigo after a head injury who has never had this kind of structural evaluation, it represents a category of care that most post-injury workups do not include. That is exactly why we want people to know it exists, and why Dr. Rumsey offers a thorough first-visit consultation before any care begins.
You Deserve Relief: Find Out if You’re a Candidate for Upper Cervical Care in Anchorage
We know what vertigo costs someone who came to Alaska to live fully in it. The Chugach trails open up for a few months a year. The fishing on the Kenai is a short window. The float planes load up and the weekends fill with the kind of outdoor living that most people in the country never get to experience. Vertigo doesn’t just cause dizziness — it grounds people who came here specifically to not be grounded.
If your vertigo traces back to a head or neck injury — whether the accident was last winter or several years ago — there is a structural question that may never have been asked. Dr. Rumsey and the team at Rumsey Spinal Care are here to ask it, with a precise evaluation that looks for what standard post-injury care is not designed to find.
You have already lost enough good days. Let us help you determine if it all boils down to a misaligned atlas bone.

Frequently Asked Questions
Why does vertigo sometimes start weeks after a head or neck injury instead of right away?
The delay happens because the brain prioritizes more acute symptoms — pain, inflammation, neurological stress — in the immediate aftermath of an injury, leaving vestibular disruption to surface gradually. At the same time, structural compensation patterns in the spine take time to accumulate. When the atlas is displaced by impact force, the mechanical stress it creates at the craniocervical junction may not reach the threshold of noticeable vertigo until weeks later, even though the underlying disruption was present from the start.
What is the difference between BPPV and cervicogenic dizziness after an injury?
BPPV involves the displacement of calcium crystals in the inner ear, producing brief episodes of spinning that are typically triggered by specific head positions — rolling over in bed, looking up, bending forward. Cervicogenic dizziness originates in the neck, where disruption to the joints, muscles, and nerves of the upper cervical spine interferes with the position and movement signals the brain uses to maintain balance. Both can result from the same head or neck injury, and both can produce ongoing vertigo. A thorough evaluation — including an upper cervical structural assessment — helps identify which piece, or combination of pieces, is most relevant.
Can whiplash cause vertigo even if I never hit my head?
Yes, and this surprises many people. The deceleration force of a whiplash mechanism — the rapid back-and-forth motion of a collision or fall — is sufficient to dislodge inner ear crystals and displace the atlas vertebra without any direct blow to the head. Patients who were told their injury was minor, or who minimized it themselves because there was no visible trauma, can still develop post-traumatic vertigo weeks later. The relevant factor is the direction and speed of force applied to the upper cervical spine, not the apparent severity of the incident.
Can post-traumatic vertigo also cause headaches, brain fog, or neck stiffness?
Yes, and when these symptoms appear together following a head or neck injury, they often point toward a single underlying structural pattern rather than several unrelated problems. The craniocervical junction — where the skull meets the upper cervical spine — is a neurologically dense region. Atlas subluxation can affect not only vestibular input but also the nerve pathways involved in head pain, cognitive clarity, and cervical mobility. Many patients at Rumsey Spinal Care come in describing vertigo as their primary complaint and discover that the headaches and brain fog they have been managing separately are part of the same picture.
How long after an injury is it still worth getting an evaluation from an upper cervical chiropractor in Anchorage?
The structural imbalance that follows a head or neck injury does not necessarily resolve on its own over time — which is part of why post-traumatic vertigo can persist for years. It also means the underlying issue is often still addressable long after the original incident. Patients who come to seek our upper cervical chiropractor in Anchorage are sometimes dealing with the downstream effects of injuries from five, ten, or more years ago. The evaluation tells us what is structurally present now, not just what happened then. If vertigo is still affecting your daily life, the timeline of the original injury is not a reason to stop looking for answers.
