Labyrinthitis: the inner-ear inflammation behind the sudden vertigo
Last updated September 3, 2026.
Labyrinthitis is the inflammation of the inner ear's labyrinth (the balance-and-hearing organ), usually after a viral infection: causing the sudden severe vertigo (constant spinning for days), often with the nausea, the hearing loss or the tinnitus in one ear, and the unsteadiness. The worst passes in days, the balance recovers over the weeks, and the vestibular-rehabilitation exercises speed the recovery.
What does it feel like?
The characteristic arc: the vertigo starts suddenly (often during or after a cold or the flu), the first days are severe (the constant spinning, the nausea and the vomiting, the needing to lie still), then the steady improvement (the spinning settling over the days, the unsteadiness and the motion-provoked dizziness lingering for the weeks). The hearing often drops or rings in one ear (that is the labyrinth being involved; when the hearing is spared, the same picture is called the vestibular neuritis). The head movements provoke the dizziness throughout the recovery.
Why does it happen?
The virus, almost always: the ordinary cold-or-flu virus inflames the labyrinth (or the nerve connecting it), the inflamed balance organ sends the mismatched signals to the brain, and the brain reads constant spinning. The bacterial kind is rare (the middle-ear infection spreading, or the meningitis) and much more serious. The one-sided damage is the rule: the healthy ear eventually compensates, which is how the recovery works.
What actually helps?
- The first days: rest, the fluids, and the short-course dizziness-and-sickness tablets (the prochlorperazine-kind: a few days only, since the longer use slows the brain's compensation).
- The vestibular rehabilitation: the balance-and-head-movement exercises (started once the worst passes) retrain the brain to rely on the healthy ear: the single best-proven speeder of the recovery.
- The early movement: the gentle normal activity, resumed as soon as tolerable, drives the compensation (the prolonged bed rest delays it).
- The hearing check: the hearing deserves the test once the acute phase passes (the persistent loss earns the ENT review).
When is it an emergency?
The red flags that are not the labyrinthitis: the severe sudden headache, the double vision, the slurred speech, the weakness or the numbness, the inability to walk at all (beyond the vertigo's unsteadiness), the high fever with the stiff neck, and the sudden complete hearing loss in one ear (the same-day kind). Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
How long will this last?
The honest arc: the severe constant spinning lasts the days (you are through it), the motion-provoked unsteadiness fades over the two-to-six weeks for most, and the full balance recovery is the usual outcome. The rehabilitation exercises shorten the whole curve, and the prolonged rest lengthens it.
Will my hearing come back?
Usually, at least partly: the viral inflammation settles and the muffled hearing improves over the weeks for most, but the hearing deserves the test once the acute phase passes, since the persistent one-sided loss needs the ENT review (and the sudden complete one-sided deafness is the same-day emergency, a different problem entirely).
Why do I still lurch when I turn my head?
The compensation in progress: the inflamed ear is still sending the weaker signal, so the quick head movements briefly outrun the brain's recalibration. It is the expected stage, not the setback, and it is exactly what the rehabilitation exercises train away.
Should I keep taking the dizziness tablets?
Only for the worst few days: the prochlorperazine-kind tablets are the mercy during the acute spinning and the vomiting, but they dampen the very brain-compensation that cures you, so the guidance is to stop them as soon as the worst passes (usually the three-to-five days) and let the exercises do the work.
Can it come back?
Unusually: the labyrinthitis is usually the one-off (the single viral hit), and the recurrence is uncommon. The more common long-tail is the mild motion-provoked unsteadiness that flares when tired or ill, manageable with the exercises. The recurring discrete vertigo attacks would suggest a different condition (the BPPV or the Meniere's) and deserve the fresh look.
When can I drive?
When the head-turn check passes: the rules require the dizziness to be settled enough for the safe control (the quick shoulder-check not provoking the lurch), which for most is the weeks, not the months. The acute phase is an absolute no.
