What to do if…
you suddenly become unsteady, unusually clumsy, or unable to walk normally

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

Short answer

Call 999 now and ask for an ambulance. Sudden unsteadiness, loss of coordination, unusual clumsiness, or difficulty walking can be a sign of a stroke or another serious condition, even if there are no obvious FAST signs or the symptoms begin to improve.

Do not do these things

  • Do not try to walk around to test whether it passes.
  • Do not drive yourself to A&E.
  • Do not wait for more symptoms before calling 999.
  • Do not dismiss the change because you are young, feel otherwise well, or have experienced dizziness before.
  • Do not take extra medicines unless the 999 call handler or a healthcare professional tells you to.
  • Do not stay alone while waiting if another person can safely remain with you.

What to do now

  1. Sit or lie down somewhere safe to reduce the risk of falling. Move away from stairs, traffic, water, hot surfaces, and sharp objects if you can do so without walking.
  2. Call 999 and ask for an ambulance. Say that the symptoms started suddenly and that you are unsteady, unusually clumsy, or unable to walk normally.
  3. Tell the call handler about any other sudden changes, such as facial drooping, weakness or numbness on one side, speech difficulty, confusion, vision changes, a severe headache, dizziness, nausea, or vomiting. Do not delay the call while checking.
  4. Note the time you were last known to be walking and coordinating normally. If you woke with the symptoms, note when you went to sleep and when you first noticed them.
  5. Ask someone nearby to stay with you, make access easier for the ambulance crew, and gather your medicines or a current medicines list if this does not delay help.
  6. Follow the call handler’s instructions. Call 999 again if your condition changes while you are waiting.
  7. If the symptoms disappear before help arrives, tell the emergency service. Sudden stroke-like symptoms still need urgent assessment after they have stopped.

What can wait

You do not need to decide whether this is a stroke, a transient ischaemic attack, vertigo, an inner-ear problem, a medicine effect, or something else. Routine appointments, online symptom searches, extensive packing, and decisions about what this could mean long term can wait.

Important reassurance

Calling 999 does not mean you are claiming to know the cause. It allows trained professionals to assess a sudden and potentially serious change promptly and avoids the risks of walking or travelling without help.

Scope note

This guide covers the first safe actions after sudden unsteadiness, clumsiness, or difficulty walking. Assessment, diagnosis, treatment, recovery, and later decisions require healthcare professionals.
