Vertigo is a specific type of dizziness where you feel like you or the room around you is spinning, even though nothing is actually moving. It’s different from feeling lightheaded or woozy. If your dizziness includes a distinct sensation of rotation or tilting, that’s vertigo. Recognizing it matters because the cause, and what to do about it, depends on the type of dizziness you’re experiencing.
What Vertigo Actually Feels Like
The hallmark of vertigo is a false sense of movement. You might feel like the walls are rotating around you, or like you’re being pulled to one side. Some people describe it as feeling like they just stepped off a spinning ride. This is fundamentally different from the faintness you might feel when you stand up too quickly or skip a meal. That lightheaded, woozy sensation is general dizziness. Vertigo always involves the illusion that something is moving when it isn’t.
Along with the spinning, you may notice nausea or vomiting, trouble keeping your balance, and a sensation that gets worse when you move your head. One physical sign that often accompanies vertigo is rapid, involuntary eye movements. Your eyes may jerk side to side, up and down, or in a circular pattern. You probably won’t notice this yourself, but someone watching you during an episode might see it, and it’s one of the key things a doctor looks for during an exam.
The Most Common Cause: BPPV
The most frequent reason people experience vertigo is a condition called BPPV (benign paroxysmal positional vertigo). It happens when tiny calcium crystals inside your inner ear shift out of place and interfere with the fluid-filled canals that help you sense balance. The result is brief, intense spinning triggered by specific head movements.
BPPV episodes typically last anywhere from a few seconds to about two minutes. They’re almost always set off by a change in head position: rolling over in bed, tilting your head back to look up, or bending forward. You feel fine when you hold still, and the spinning hits only when you move. That pattern of short bursts tied to specific movements is the clearest sign that BPPV is the cause. Between episodes, you may feel completely normal.
To confirm BPPV, a provider performs a simple bedside test. You sit on an exam table, they turn your head 45 degrees to one side, then quickly guide you to lie back so your head hangs slightly over the edge with one ear pointing toward the floor. They watch your eyes for those involuntary jerking movements. If the movements appear, the test is positive, and it also tells them which ear contains the displaced crystals. If no eye movements show up, something else is likely causing your vertigo.
Vertigo That Lasts Hours: Ménière’s Disease
If your vertigo episodes last much longer than a couple of minutes, Ménière’s disease is one possibility. This inner ear disorder causes spinning episodes that last anywhere from 20 minutes to 12 hours, and it comes with a distinct cluster of symptoms: ringing in the ear (tinnitus), hearing loss that tends to affect lower-pitched sounds, and a feeling of fullness or pressure in the affected ear, almost like it’s stuffed with cotton.
A diagnosis typically requires at least two spontaneous episodes of vertigo in that 20-minute to 12-hour range, plus documented hearing changes on a hearing test. The hearing loss and ear symptoms may come and go irregularly, which can make it confusing early on. But if your vertigo consistently shows up alongside muffled hearing, ringing, and ear pressure, that combination is a strong signal.
Vertigo From Infection or Inflammation
Sometimes vertigo comes on suddenly and sticks around for days rather than minutes or hours. Two related conditions cause this: vestibular neuritis and labyrinthitis. Both involve inflammation in the inner ear, usually following a viral infection.
The key difference between the two is hearing. Vestibular neuritis affects the nerve that sends balance signals to your brain, causing prolonged vertigo without significant hearing loss. Labyrinthitis affects a broader area of the inner ear and causes both prolonged vertigo and hearing loss. In either case, you’ll feel dizzy constantly, not just when you move your head. Any head movement makes it worse, but you’re symptomatic even at rest. The intense phase usually eases over days to a few weeks, though some people feel residual unsteadiness for longer.
Vertigo and Migraines
If you have a history of migraines, your vertigo episodes may be connected. Vestibular migraine causes moderate to severe spinning that can last anywhere from five minutes to 72 hours. At least half the episodes tend to come with typical migraine features: a one-sided, pulsating headache that gets worse with physical activity, sensitivity to light and sound, or visual disturbances like seeing flashing lights or zigzag lines.
This type of vertigo can be tricky to pin down because the headache doesn’t always show up during every episode. Some people get the spinning without any head pain at all. The connection becomes clearer over time as a pattern emerges across multiple episodes.
When Vertigo Signals Something Serious
Most vertigo comes from inner ear problems and, while miserable, isn’t dangerous. But in roughly 10% to 20% of people who develop sudden, continuous vertigo, the cause is a stroke affecting the brainstem or cerebellum. This is why recognizing the pattern of your symptoms matters.
The red flags that separate a possible stroke from an inner ear problem come down to a few distinctions. Stroke-related vertigo tends to be constant rather than triggered by specific head positions. You’re dizzy at rest, and any head movement makes it worse. You may also notice new symptoms that don’t fit with an ear problem: difficulty walking or coordinating movements, double vision, slurred speech, numbness or weakness on one side of the body, or trouble swallowing. Sudden hearing loss in one ear can also be a warning sign.
In emergency settings, doctors use a specific three-part eye exam that checks how your eyes respond to quick head turns, whether your eye movements follow a normal or abnormal pattern, and whether your eyes are vertically misaligned. This bedside test, combined with a check for hearing loss, is actually more accurate at ruling out stroke than an early MRI brain scan. MRI misses about 20% of strokes in the first 24 to 48 hours, while the bedside eye exam catches over 99% when performed by a trained clinician. If you develop sudden, continuous vertigo with any neurological symptoms, that warrants emergency evaluation.
Sorting Out What You’re Experiencing
The most useful thing you can do is pay attention to three details: how long your episodes last, what triggers them, and what other symptoms come with them. These details are what separate the different causes and will be the first things a provider asks about.
- Seconds to two minutes, triggered by head position changes: likely BPPV
- Twenty minutes to several hours, with ear pressure, ringing, and hearing changes: suggests Ménière’s disease
- Days of constant dizziness after a cold or infection: points to vestibular neuritis or labyrinthitis
- Five minutes to 72 hours, with migraine features: consistent with vestibular migraine
- Sudden and constant, with neurological symptoms like weakness or double vision: needs immediate medical attention
Keeping a brief log of your episodes, noting when they happen, how long they last, and what you were doing when they started, gives you and your provider a much clearer picture. Vertigo is a symptom, not a diagnosis, and the pattern it follows is the fastest path to figuring out what’s behind it.
