Vestibular neuritis: the inflamed balance nerve behind the sudden vertigo
Last updated September 3, 2026.
Vestibular neuritis is the inflammation of the vestibular nerve (the balance nerve from the inner ear to the brain), usually after a viral infection: causing the sudden severe constant vertigo for days, with the nausea and the unsteadiness, but the normal hearing. It is the close cousin of the labyrinthitis (same illness, hearing spared), the worst passes in days, and the balance recovers over the weeks with the vestibular-rehabilitation exercises.
What does it feel like?
The sudden onset, often during or just after a cold: the constant spinning (not the position-triggered seconds of the BPPV: this one spins regardless), the severe nausea and the vomiting in the first days, the unsteadiness that keeps you horizontal, and then the steady improvement: the spinning settling over the days, the motion-provoked dizziness and the lurching lingering for the weeks. The hearing stays normal throughout (the muffled or the lost hearing makes it the labyrinthitis instead).
Why does it happen?
The viral inflammation of the balance nerve: the ordinary cold-or-flu virus (or the reactivated herpes-family virus) inflames the nerve on one side, the inflamed nerve stops sending the balance signals, and the brain receives the mismatched input (one ear reporting, one ear silent) and reads the constant spinning. The compensation is the cure: over the weeks the brain rewires to run on the one healthy ear, aided by the movement and the exercises.
What actually helps?
- The first days: rest, the fluids, and the short-course sickness-and-dizziness tablets (the prochlorperazine-kind: the few days only, since the longer use delays the compensation).
- The vestibular rehabilitation: the head-movement-and-balance exercises, started once the acute spinning settles, are the best-proven treatment: they train the brain to trust the healthy ear.
- The early movement: the normal activity resumed as soon as tolerable (the brain's compensation feeds on the movement; the prolonged bed rest slows it).
- The follow-up if slow: the unsteadiness persisting past the six-to-eight weeks earns the physio or the balance-clinic review.
When is it an emergency?
The red flags that are not the neuritis: the severe sudden headache, the double vision, the slurred speech, the weakness or the numbness, the new hearing loss (that changes the diagnosis and the urgency), the inability to walk at all, and the fever with the stiff neck. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
How is this different from labyrinthitis?
One organ, two cousins: the same viral inflammation, but the neuritis spares the hearing (only the balance nerve inflamed) while the labyrinthitis takes the hearing too (the whole labyrinth inflamed). The vertigo, the treatment, and the recovery are the same; the hearing is the dividing line, and the new hearing loss always deserves the fresh assessment.
How long until I feel normal?
The usual arc: the constant spinning settles within the first week (yours has), the walk-around unsteadiness fades over the two-to-six weeks for most, and the full recovery is the rule. The rehabilitation exercises shorten the tail, and the rare slow-burner gets the balance-clinic review at the six-to-eight weeks.
Why do quick head turns still make me lurch?
The nerve is still underperforming: the quick movements need the instant, accurate balance signal, and the recovering nerve delivers it late, so the brain briefly misreads. It is the expected recovery stage, and it is precisely what the gaze-stability exercises (the head-turns-while-focusing kind) train away.
Should I keep taking the sickness tablets?
No, if the acute phase has passed: the tablets are the mercy for the first spinning-and-vomiting days, but they dampen the brain's compensation (the process that actually cures you), so the guidance is the few days only. By a week in, the movement is the medicine.
Will it happen again?
Uncommonly: the vestibular neuritis is usually the one-off, and the true recurrence is rare. What some people notice instead is the mild unsteadiness flaring when run-down or ill (the decompensated moments: brief, self-settling). The recurring discrete spinning attacks would point elsewhere (the BPPV, the Meniere's) and deserve the fresh look.
When can I drive and go back to work?
The drive when the quick head-check no longer provokes the lurch (the shoulder-check test: the driving needs it clean), usually the few weeks. The work depends on the job: the desk work returns early (the slow movements), the heights, the ladders, and the machinery wait for the full steadiness.
