What to do if…
you develop sudden spinning dizziness and have to lie down

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Lie down somewhere safe, keep your head still, and check for stroke warning signs. If you have face drooping, arm weakness or numbness, speech trouble, new confusion, sudden vision loss, double vision, sudden hearing loss, sudden severe headache, or sudden trouble walking or standing, call 999 now.

Do not do these things

  • Do not try to push through it or walk unaided; spinning vertigo can make falls more likely.
  • Do not drive yourself anywhere, including to A&E.
  • Do not drink alcohol or take extra sedating medicines to knock it out; only take medicines as directed or prescribed, and do not take someone else’s medication.
  • Do not go into a bath or shower alone, use stairs, climb, or use machinery while it is spinning.
  • Do not ignore new weakness, numbness, slurred speech, new confusion, new vision loss, double vision, sudden hearing loss, or a sudden severe headache, even if the spinning eases.

What to do now

  1. Make the situation physically safe.
    Lie flat, or slightly propped up if that reduces nausea. Keep your head as still as you can. If you might vomit, roll onto your side and keep a bowl or bag nearby.

  2. Do a quick emergency screen.
    Check:

    • Face: can you smile evenly?
    • Arms: can you lift both arms and keep them up?
    • Speech: is your speech clear?
    • Balance: can you stand or walk safely with support, or are you suddenly falling over?
    • Vision and hearing: is there new vision loss, double vision, or sudden hearing loss?
    • Headache: is there a sudden severe headache?

  3. Call 999 now if any emergency sign is present, or you are not sure.
    Say: “Sudden onset spinning dizziness or vertigo, started at [time], I had to lie down.” Do not attempt to travel yourself. Call even if the signs improve, because stroke-like symptoms still need urgent medical assessment.

  4. If there are no emergency signs but the vertigo is severe, new, or worrying, get same-day urgent advice.
    Call 111 where available, or use your local urgent care route. In England, NHS 111 online can also direct you. This is especially important today if you are being sick or feel very sick, have a severe headache, have a very high temperature, feel hot and shivery, or cannot safely move around.

  5. If you are alone, get another person involved.
    Call or text a neighbour, friend, or family member to sit with you, help you move safely, and call for help if you get worse.

  6. Write down four details for clinicians.
    Use phone notes if that is easiest:

    • the exact start time
    • what you were doing when it began, such as rolling in bed, turning your head, or standing up
    • any ear symptoms, such as sudden hearing change, ringing, pressure, or ear pain
    • any nerve-type symptoms, such as weakness, numbness, speech problems, vision changes, confusion, or severe headache

  7. If you can swallow safely and you are not actively vomiting, take small sips of water.
    If you are actively vomiting, very drowsy, or struggling to swallow, do not force fluids. Focus on safe positioning and getting urgent advice.

What can wait

  • You do not need to work out the cause right now.
  • You do not need to try online manoeuvres or exercises during a severe first episode.
  • You do not need to sort work messages, driving plans, chores, or appointments until you have been assessed or are clearly improving.

Important reassurance

Sudden spinning vertigo can feel frightening, and needing to lie down can happen with vertigo. Many causes are treatable or settle, but sudden dizziness and imbalance can sometimes be part of a stroke, so checking the emergency signs first is the safest first step.

Scope note

These are first steps only, to help you stay safe and get the right urgent help. Diagnosis and later treatment decisions may need a clinician or specialist.

Important note

This is general information, not medical diagnosis or professional medical advice. If symptoms are severe, new, worsening, or you have any stroke warning signs, seek urgent medical help immediately.
