Sudden Severe Vertigo: The Red Flags That Mean Call 108 Now

If the room is suddenly spinning hard and you are frightened, take a slow breath. Most vertigo comes from the inner ear and is not dangerous, even when it feels violent and makes you sick. But a small number of sudden spinning spells are the body's way of signalling something serious in the brain, and those need help within minutes, not a wait-and-watch approach at home.

This article is about telling those two situations apart. Read the red flags first. If any of them fit what is happening to you right now, stop reading and call 108.

Call 108 now if any of these are happening

Do not drive yourself. Do not wait for it to settle. If the spinning came on suddenly and severely, and it comes with any of the signs below, treat it as a possible stroke and call 108 or get to the nearest emergency department at once.

• Slurred, slow or garbled speech, or sudden trouble finding words
• A droop on one side of the face, or a numb, drooping mouth
• Double vision, or loss of part of your field of sight
• Weakness, heaviness or numbness in an arm or a leg, usually on one side
• Severe unsteadiness, or being unable to stand or walk even with support
• The worst, most sudden headache of your life (a thunderclap headache)
• New confusion, fainting, or difficulty swallowing along with the spinning

Any one of these with sudden vertigo is enough. You do not need to have all of them. It is always safer to be checked and sent home than to talk yourself out of calling. Vomiting on its own, or spinning that eases when you keep your head very still, is common with harmless inner-ear vertigo, but if you are unsure, call.

Why the first hour counts

When vertigo comes from a problem in the brain's blood supply, the care that protects you works best when it is given early. That is the whole reason to call 108 rather than book an appointment for the next day. An emergency department can scan the brain and start the right treatment quickly. An outpatient ENT clinic cannot do that, and this clinic is not an emergency service. If the red flags fit, the hospital comes first, always.

What ordinary inner-ear vertigo tends to look like

Most vertigo we see is peripheral, meaning it starts in the balance organs of the inner ear rather than the brain. It can be intense and can leave you clinging to the bed, but it usually behaves in recognisable ways. The table below is a rough guide to help you think clearly, not a substitute for being examined.

Common causes an ENT can help sort out later

Once an emergency has been ruled out, or if your symptoms never carried any red flags in the first place, several familiar conditions can explain the spinning. An ENT can assess these, treat the inner-ear ones, and, where a problem such as migraine-related dizziness needs care beyond the ear, point you toward the right help.

• BPPV, where tiny crystals in the inner ear slip out of place and brief spinning is set off by a change in head position. It is common and often very responsive to the right treatment.
• Vestibular neuritis or labyrinthitis, often after a viral illness, causing days of constant spinning that slowly settles.
• Meniere's disease, with episodes of spinning, a blocked feeling and changing hearing in one ear.
• Vestibular migraine, where the balance system is caught up in a migraine pattern, sometimes with little or no headache at all. This is driven by migraine rather than the ear itself, so it may need migraine-focused care alongside an ENT assessment.

In clinic, an ENT can take your history, examine your ears and balance at the bedside, and do positional testing such as the Dix-Hallpike to check for BPPV. If a specific affected canal is confirmed, a canalith repositioning treatment (the Epley manoeuvre) can be done in clinic, though we cannot promise it will happen the same day, or that a single session settles everything. You may be taught simple Brandt-Daroff exercises to do at home, and offered a hearing test (audiometry) if your hearing is involved. Relief comes from getting the diagnosis right, not from a quick trick.

After the emergency is ruled out, we are here
