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

Short answer

Call 999 now and say you have new weakness in both legs or worsening trouble walking over a few hours. Mention straight away if you have breathing difficulty, swallowing difficulty, new bladder or bowel changes, saddle-area numbness, severe back pain, or stroke-type symptoms.

Do not do these things

  • Do not drive yourself to A&E.
  • Do not try to push through it, walk it off, use stairs, shower, or bathe while your legs are unreliable.
  • Do not keep standing or walking to test it if you feel unsafe or it is getting worse.
  • Do not ignore new bladder or bowel changes, even if they happened only once.
  • Do not ignore numbness or tingling between your legs, around your genitals, or around your anus or bottom.
  • If swallowing feels unsafe, your speech is slurred, or you are very drowsy or confused, do not eat or drink while waiting for help.

What to do now

  1. Call 999 now.

    • Use speakerphone if you can.
    • Say: “New weakness in both legs or worsening trouble walking over a few hours.”
    • Say where you are and whether you are alone.
  2. Get into the safest position you can.

    • Sit or lie down on a bed, sofa, or floor.
    • Keep your phone within reach.
    • If you live alone, unlock the door if it is safe to do so.
  3. Tell the 999 call handler clearly if any of these are happening.

    • You cannot pass urine, have new leakage, or have lost bowel control.
    • You have numbness or tingling between your legs, around your genitals, or around your anus or bottom.
    • You have severe back pain, a recent fall or injury, fever, or weakness or numbness spreading quickly.
    • You have face drooping, arm weakness, slurred speech, confusion, sudden severe headache, new vision problems, dizziness, falling over, or sudden balance problems.
    • You have breathing problems, swallowing problems, facial weakness, or weakness spreading upwards.
  4. Make a very short timeline.

    • Write or text when the symptoms started.
    • Add when walking clearly became worse.
    • Add any bladder, bowel, numbness, pain, injury, fever, breathing, swallowing, speech, face, or arm symptoms.
  5. Put essential information in one place while you wait.

    • Medication packets or a medication list.
    • Allergies.
    • Key medical conditions.
    • GP details if they are easy to find.
    • Any blood thinner medication or recent medication changes.
  6. Ask someone nearby to stay with you if possible.

    • Ask them to help prevent falls.
    • Ask them to listen for the ambulance crew or any call back.
    • Ask them to pass on your timeline and medication information if you find it hard to speak.

What can wait

  • You do not need to work out the cause now.
  • You do not need to search symptoms or decide which condition it sounds like.
  • You do not need to pack properly.
  • You do not need to contact work, cancel plans, or update lots of people.
  • You do not need to decide what tests or treatment you might need.

Important reassurance

Sudden or rapidly worsening walking trouble is frightening, and calling 999 is a reasonable safety step. It does not mean you know the cause; it means you are getting checked quickly because some causes need urgent treatment to reduce harm.

Scope note

These are first steps only for the next few hours. After you are assessed, clinicians may advise examination, scans, blood tests, monitoring, treatment, or specialist review depending on what they find.

Important note

This guide is general information, not a diagnosis, and it is not medical or professional advice. For new weakness in both legs or worsening trouble walking over a few hours in the UK, call 999 and follow the advice you are given.
