You glance over your shoulder to change lanes and the world tilts for a second. Or you roll over in bed at 3 a.m. and the room spins hard enough to grab the mattress. Patients at Atlas Chiropractic in Fort Wayne often arrive having been told it’s “probably an inner ear thing,” without anyone checking. The two most common movement-triggered causes behave differently, and the details you notice at home usually point toward one or the other.
What’s the difference between vertigo and dizziness?
Vertigo is a false sense of motion, usually spinning, as if you or the room is turning. Dizziness is the broader term and also covers feeling lightheaded, off balance, foggy, or like the floor is shifting.
The words matter. Spinning points clinicians toward the inner ear and brain, while unsteadiness opens a wider list that includes the neck.
Why does rolling over in bed point to the inner ear?
Because the most common cause of vertigo, benign paroxysmal positional vertigo (BPPV), is triggered by changing your head’s position relative to gravity. Tiny calcium crystals drift into one of the inner ear’s balance canals and send a false spinning signal when your head moves.
The American Academy of Otolaryngology-Head and Neck Surgery’s clinical practice guideline, updated in 2017, calls BPPV the most common inner ear cause of vertigo and notes that episodes generally last less than a minute. Typical triggers include lying down, rolling over, and looking up at a high shelf.
BPPV is diagnosed with the Dix-Hallpike test, in which a clinician moves you from sitting to lying back with your head turned 45 degrees and slightly extended while watching your eyes for a characteristic flicker called nystagmus. It’s usually treated with a repositioning maneuver such as the Epley, done by a physician or vestibular physical therapist.
What does neck-driven dizziness feel like?
Cervicogenic dizziness, meaning dizziness that comes from the neck, tends to feel like unsteadiness or a floating sensation rather than a hard spin. It usually comes with neck pain or stiffness and follows neck movement or sustained postures.
Think turning to back out of a driveway, an hour at a laptop, or the weeks after whiplash. Episodes tend to last minutes to hours, not seconds. A 2017 review in Archives of Physiotherapy by Reiley and colleagues at Duke University points out that no single test confirms it. Cervicogenic dizziness is a diagnosis of exclusion, reached after inner ear, neurological, and vascular causes have been ruled out.
Why can a neck problem affect balance at all?

Your brain balances you using three inputs: the inner ear, your eyes, and position sensors in the upper neck, which are densely packed into the small suboccipital muscles at the base of the skull.
When the upper neck is strained or sitting off its normal position, its signal can disagree with what your eyes and inner ears report. The brain registers the mismatch as unsteadiness.
Is there a simple way to tell them apart?
BPPV responds to the head’s position relative to gravity. Neck-driven dizziness responds to the neck’s position relative to the body.
Clinicians test this with a neck torsion test: you sit on a swivel chair while your head is held still and your body is rotated underneath it. Your inner ear doesn’t move, but your neck does. Dizziness that appears this way points toward the neck.
Other clues:
- Spinning for under a minute when lying down or rolling over leans toward BPPV.
- Unsteadiness with neck pain after turning your head or sitting at a screen leans toward the neck.
- Hearing loss, ringing, or ear fullness during episodes points toward an ear specialist.
Which dizziness needs emergency care first?
Call 911 if dizziness comes on suddenly with slurred speech, double vision, facial drooping, weakness or numbness on one side, trouble walking, or a sudden severe headache. These can be signs of a stroke in the back of the brain, which sometimes starts with dizziness alone. Sudden severe neck pain with dizziness after trauma also needs emergency evaluation to rule out an injured artery.
How does Atlas Chiropractic evaluate dizziness?
Atlas Chiropractic starts with history: when the dizziness began, what triggers it, how long episodes last, and what happened to your head and neck in the months before. If the pattern points to BPPV or anything neurological, Dr. Emily refers you to the right provider first.
When the upper neck is a likely contributor, the NUCCA exam measures it. Precision imaging quantifies how the atlas sits in degrees, alongside a supine leg check, postural measurements, and cervical range of motion. Follow-up imaging confirms whether a correction changed those numbers.
Dizziness that follows head movement isn’t always the inner ear, and it isn’t always the neck. Atlas Chiropractic helps Fort Wayne patients sort out which one it is and measures the upper cervical spine when the history points there.
