Most vertigo is caused by inner ear problems that resolve on their own, but certain patterns of symptoms signal something more serious that needs prompt medical attention. The short answer: if your vertigo comes with slurred speech, facial or limb weakness, numbness on one side of your body, or a sudden inability to walk, treat it as a medical emergency. Outside of those red flags, vertigo that keeps coming back, lasts more than a few days, or arrives alongside hearing changes deserves a doctor’s appointment sooner rather than later.
Symptoms That Require Emergency Care
The biggest concern with vertigo is that it can occasionally be caused by a stroke in the back of the brain, which controls balance. A stroke-related vertigo episode can look almost identical to a harmless inner ear infection at first, so the distinguishing features matter. Focal numbness, focal weakness, and slurred speech are the clearest warning signs that the problem is in your brain rather than your ear. If you notice any of these alongside the spinning sensation, call emergency services immediately.
Another red flag is being completely unable to walk. People with inner ear problems feel unsteady on their feet, but they can still get around. If the room is spinning and you physically cannot stand or take steps, that points toward a central nervous system cause. The same applies to a severe, sudden headache unlike anything you’ve experienced before, or a new loss of coordination in your arms or hands.
One symptom that might seem alarming but is less reliable as a red flag is mild double vision. A peripheral (ear-related) vestibular problem can produce mild double vision on its own, so it doesn’t automatically mean something dangerous is happening. That said, if double vision is severe or accompanied by any of the other signs above, err on the side of getting emergency evaluation.
When Vertigo Likely Points to BPPV
The most common cause of vertigo is benign paroxysmal positional vertigo, or BPPV. It happens when tiny calcium crystals in your inner ear drift into the wrong canal and send false motion signals to your brain. The hallmark of BPPV is that each episode is brief, typically lasting under one to two minutes, and is triggered by a specific change in head position: rolling over in bed, tipping your head back in the shower, or looking up at a high shelf.
BPPV isn’t dangerous, but it’s worth seeing a doctor if episodes keep recurring or if you’re unsure that’s what you have. A clinician can confirm the diagnosis with a simple head-positioning test in the office and often fix the problem in one visit using a guided series of head movements that shift the crystals back where they belong. If your “BPPV” episodes last longer than a couple of minutes, happen without any head movement trigger, or come with hearing changes, something else is going on.
Vertigo Lasting Days: Vestibular Neuritis
If you wake up one morning with severe, constant spinning that doesn’t let up for hours or days, the most likely culprit is vestibular neuritis, an inflammation of the nerve connecting your inner ear to your brain. It’s usually caused by a viral infection. The acute phase, where the spinning is intense and you may vomit, typically lasts days to weeks.
Here’s the important part: about 50% of people with vestibular neuritis go on to experience chronic dizziness, unsteadiness, or a vague sense of spatial disorientation long after the acute spinning stops. If you’re still feeling off-balance or dizzy weeks after an episode, that’s a clear reason to see a doctor. Vestibular rehabilitation therapy, a specialized form of physical therapy, can significantly speed recovery by retraining your brain to compensate for the damaged nerve signals. The longer you wait, the more entrenched those chronic symptoms can become.
Recurring Episodes With Hearing Changes
Vertigo that comes back repeatedly and is accompanied by hearing loss, ringing in the ear, or a feeling of fullness or pressure in one ear may indicate Ménière’s disease. The diagnostic pattern is specific: episodes of spontaneous vertigo lasting anywhere from 20 minutes to 12 hours, with fluctuating hearing symptoms in the affected ear. The key word is “fluctuating,” meaning your hearing, tinnitus, or ear fullness come and go rather than staying constant.
If you’ve had two or more episodes fitting this description, bring it up with your doctor. Ménière’s involves excess fluid buildup in the inner ear, and while there’s no cure, treatments can reduce the frequency and severity of attacks. Any sudden hearing loss that appears alongside vertigo deserves urgent attention regardless of the suspected cause, because early treatment gives you the best chance of recovering that hearing.
Vertigo With Migraine Features
Vestibular migraine is one of the most underdiagnosed causes of recurring vertigo. It produces moderate to severe episodes of dizziness or spinning that last anywhere from five minutes to 72 hours. What sets it apart is that at least half the episodes come with migraine features: a one-sided, pulsating headache that gets worse with physical activity, sensitivity to light and sound, or visual disturbances like bright zigzag lines or shimmering spots that expand over 5 to 20 minutes.
You don’t need to have a headache during every episode for this to be the cause. Many people with vestibular migraine have a history of migraines earlier in life, even if the headaches have faded and the vertigo is now the main symptom. If you’ve had five or more episodes matching this pattern, a neurologist can help with both diagnosis and a preventive treatment plan.
Dizziness That Won’t Go Away for Months
Some people develop a persistent, low-grade dizziness or unsteadiness that hangs around for months after an initial vertigo episode. If you feel dizzy or off-balance on most days for three months or more, and the sensation gets worse when you’re standing, moving around, or in visually busy environments like grocery stores or scrolling on your phone, this pattern has a name: persistent postural-perceptual dizziness, or PPPD.
PPPD often starts after a triggering event like BPPV, vestibular neuritis, or even a panic attack, then takes on a life of its own. It’s driven by the brain over-relying on certain balance strategies that are no longer helpful. It responds well to vestibular rehabilitation and, in some cases, medications that calm the brain’s threat-detection system. The takeaway: if months have passed and you’re still not feeling right, that’s not normal lingering symptoms. It’s a treatable condition worth getting evaluated.
Medications That Can Cause Vertigo
Before assuming your vertigo has an inner ear or brain cause, consider your medication list. Several common drug classes can trigger vertigo as a side effect. Anticonvulsants like pregabalin and phenytoin are frequent offenders. Blood pressure medications, including calcium channel blockers, certain diuretics, and alpha-blockers, can also cause it. Heart medications like some beta-blockers and nitrates round out the list.
Some of these medications are also directly toxic to the inner ear. If you’re taking a drug known to carry that risk and you develop vertigo, a dose adjustment or switch to an alternative may be necessary to prevent permanent hearing damage. Don’t stop any prescription on your own, but do flag the vertigo for your prescribing doctor, especially if it started shortly after beginning a new medication or increasing a dose.
ENT Specialist vs. Neurologist
If your primary care doctor refers you to a specialist, the choice between an ear, nose, and throat doctor (ENT) and a neurologist depends on the suspected cause. Ear-related vertigo, including BPPV, Ménière’s disease, and vestibular neuritis, typically falls under ENT or a subspecialist called a neurotologist. If the pattern suggests vestibular migraine, PPPD, or if there are neurological symptoms or a history of conditions like multiple sclerosis or Parkinson’s disease, a neurologist is the better fit.
In emergency settings, doctors use a bedside eye-movement exam that has proven more sensitive than even an early MRI for detecting stroke as a cause of vertigo. MRI can miss small strokes in the first 48 hours up to 12% of the time, while this clinical exam catches central causes with roughly 90 to 96% accuracy. This is worth knowing because if you go to the ER with vertigo and a normal brain scan, it doesn’t always rule out something serious. Insist on a thorough neurological evaluation if your symptoms include any of the red flags described above.
