Quick answer
Severe spinning vertigo days or weeks after a viral fever is often vestibular neuritis, an inflammation of the balance nerve. It causes sudden vertigo for one to several days, nausea and imbalance, usually without hearing loss. It is not dangerous, but vertigo with speech difficulty, weakness, double vision or severe headache may be a stroke. Vestibular rehabilitation speeds recovery.
Key takeaways
- Hyderabad hospitals have reported a surge in viral fevers and flu-like illness since August 2026, and post-viral vertigo typically follows.
- Vestibular neuritis: sudden severe vertigo for 1–several days, then weeks of unsteadiness.
- Red flags for stroke: speech difficulty, one-sided weakness, double vision, severe headache, inability to walk, sudden hearing loss.
- Vertigo-suppressant tablets should be stopped after 1–3 days; they delay recovery if continued.
- Early vestibular rehabilitation gives faster and more complete recovery than bed rest.

Hyderabad has had a long season of viral fevers, flu-like illness and respiratory infections, with hospitals reporting a surge since August. For most people the fever passes in a week. But a few wake up days or weeks later with the room spinning violently, unable to stand, vomiting and terrified it is something serious.
This is often vestibular neuritis, an inflammation of the balance nerve that usually follows a viral infection. It is frightening, but it is not dangerous, and with the right treatment most people recover well. This guide explains the signs, how it differs from a stroke, how it is diagnosed, and why vestibular rehabilitation speeds recovery.
What is vestibular neuritis?
The vestibular nerve carries balance information from the inner ear to the brain. In vestibular neuritis, this nerve becomes inflamed, usually after a viral infection such as flu, a cold or another viral illness. The brain suddenly receives strong signals from one ear and weak signals from the other, and interprets the mismatch as spinning.
When the hearing part of the nerve is also affected and hearing drops, the condition is called labyrinthitis.
Symptoms of vestibular neuritis
- Sudden, severe spinning vertigo that starts over minutes to hours and lasts for one to several days.
- Nausea and vomiting.
- Severe imbalance, with a tendency to fall or veer to one side.
- Vertigo made worse by any head movement, so patients lie still.
- Jerking eye movements (nystagmus) that others may notice.
- Usually no hearing loss and no ringing (if hearing is affected, it may be labyrinthitis).
- Often a recent fever, cold or flu in the preceding one to three weeks.
After the first few days, the intense spinning settles, but unsteadiness, a swimming sensation and dizziness with quick head turns can last for weeks or months, especially if the brain is not helped to compensate.
Is it a stroke? Red flags that need emergency care
Sudden vertigo can, rarely, be caused by a stroke in the back of the brain, and the two can look alike. Go to an emergency department immediately if vertigo comes with any of these:
- Difficulty speaking or slurred speech.
- Weakness, numbness or clumsiness in the face, arm or leg.
- Double vision, loss of vision or drooping of one side of the face.
- A sudden severe headache or neck pain.
- Inability to walk at all, even with support.
- Sudden hearing loss in one ear.
If you are over 50, have diabetes, high blood pressure, heart disease or have had a stroke before, be extra cautious and seek urgent assessment for any sudden vertigo.
How is vestibular neuritis diagnosed?
A vertigo specialist diagnoses it from the history and a careful examination of eye movements and balance. Key tests include:
- Head impulse test, performed by hand or with video goggles (vHIT), which shows whether the balance reflex on one side is weak.
- Examination of nystagmus and positional testing to rule out BPPV.
- Videonystagmography (VNG) and caloric testing, which measure how each inner ear responds.
- Hearing test, to distinguish neuritis from labyrinthitis and other causes.
- Imaging (MRI) only when there are red flags or atypical findings.
A detailed vestibular evaluation also rules out other causes of post-viral dizziness, such as BPPV (which can be triggered by lying in bed during illness), vestibular migraine, dehydration, low blood pressure and medication side effects.
How is vestibular neuritis treated?
1. Short-term relief
For the first one to three days, a doctor may prescribe medicines for nausea and vertigo, and sometimes a short course of steroids if started early. Vertigo-suppressant tablets should be stopped as soon as possible, because they slow the brain’s recovery if taken for long.
2. Vestibular rehabilitation therapy (VRT)
This is the most important treatment. The damaged nerve may not recover fully, but the brain can learn to rebalance the signals, a process called compensation. VRT is a programme of gaze-stabilisation, balance and walking exercises that drives compensation. Studies show that people who start VRT early recover faster and more completely than those who rest and wait.
3. Keep moving
Lying still for weeks delays recovery. Once the worst spinning has settled, gentle, gradual movement and the prescribed exercises are what get you better.
Most people improve substantially within a few weeks, and the majority recover their balance within two to three months with rehabilitation. A minority have lingering dizziness, which also responds to VRT.
How a virus reaches the balance nerve
The vestibular nerve runs from the inner ear to the brainstem. Viruses that cause common fevers, flu and cold-like illnesses can inflame this nerve directly or trigger an immune reaction that does. Because the nerve is housed in a tight bony canal, swelling quickly disrupts its signals. The brain, suddenly receiving mismatched information from the two ears, reacts with intense vertigo. The balance nerve on the affected side may recover partly, fully or not at all. Recovery of balance depends less on the nerve and more on how well the brain learns to compensate, which is where rehabilitation comes in.
Other causes of dizziness after a fever
Not every post-fever dizziness is neuritis. Our assessment also checks for:
- Dehydration and weakness, which cause light-headedness on standing rather than spinning.
- BPPV, which can be triggered by days of lying in bed and causes brief spinning with head position changes.
- Vestibular migraine, which may flare after illness and causes recurring vertigo with headache, light sensitivity or visual symptoms.
- Medication effects, including some antibiotics and anti-nausea drugs.
- Low blood pressure or anaemia after illness.
- Ear infection spreading to the inner ear (labyrinthitis), which also affects hearing.
Each has a different treatment, so a precise diagnosis is essential.
A typical recovery timeline
| Phase | What you may feel | What to do |
| Days 1–3 | Severe spinning, vomiting, cannot stand | Rest, fluids, short-term medicines if prescribed |
| Days 4–14 | Spinning settles; unsteady, worse with head movement | Start moving; begin vestibular rehabilitation |
| Weeks 3–8 | Improving balance; dizzy in busy places or with quick turns | Progress exercises; return to work and driving when safe |
| Months 2–3 | Near-normal for most people | Finish programme; reassess if symptoms persist |
What vestibular rehabilitation involves after neuritis
Rehabilitation is tailored to test results and symptoms, and typically includes gaze-stabilisation exercises (keeping the eyes fixed on a target while the head moves), balance exercises on different surfaces with eyes open and closed, walking with head turns, and gradual exposure to busy visual environments such as supermarkets and traffic. Sessions start gently and progress every week or two. Exercises may bring on mild dizziness; that is the signal the brain needs to adapt. Severe or new symptoms should be reported.
Returning to normal life safely
Do not drive until you can turn your head quickly without vertigo. Avoid heights and ladders while unsteady. Return to work gradually, especially if your job involves screens, which can provoke dizziness during recovery. Keep hydrated, sleep well and keep moving. Fear of movement is one of the biggest obstacles to recovery, and a supervised programme gives most people the confidence to get back to normal.
