What to do if…
you notice new numbness in the groin area or trouble controlling your bladder or bowels

Short answer

Treat this as urgent: go to A&E now (or call 999 if you can’t safely get there). These symptoms can be a warning sign of serious spinal nerve compression that needs rapid assessment.

Do not do these things

  • Don’t “wait and see” or try to sleep it off.
  • Don’t book a routine GP/physio appointment as your next step.
  • Don’t drive yourself if your legs feel weak/numb, you’re dizzy, or you’re in severe pain—get help with transport.
  • Don’t take alcohol or extra sedating medicines (beyond what you’re prescribed). Don’t stop prescribed medicines unless a clinician tells you to.
  • Don’t assume it’s “just a pulled muscle” because the back pain isn’t severe.

What to do now

  1. If you can’t pass urine at all, have rapidly worsening leg weakness, severe pain, or you feel unsafe at home: call 999 and say you have new groin/saddle numbness and bladder/bowel control problems and need urgent assessment.
  2. Go to your nearest A&E now. If possible, ask someone to take you or call a taxi rather than driving yourself.
  3. If you can’t get to A&E and it doesn’t feel like a 999 emergency: call NHS 111 immediately and say you have new groin/saddle numbness and new bladder/bowel control problems. Ask what the fastest route into emergency assessment is (they may advise A&E or arrange an ambulance).
  4. Use clear words at triage:
    “I have new numbness in the groin/saddle area and new trouble controlling my bladder/bowels (or trouble starting to pee / leaking / not feeling when I’m full). I’m worried about cauda equina / spinal nerve compression.”
  5. Note the timing and changes (write it in your phone):
    • When the numbness started (even approximate time).
    • What’s changed with peeing/pooing (can’t start, can’t stop, leaking, can’t feel it, can’t tell if full).
    • Any leg symptoms (numbness, weakness, pain down one/both legs).
    • Any recent triggers (fall/injury; recent spinal procedure/epidural; known disc problems).
  6. Take essentials: a medication list (or photos of labels), allergies, NHS number if you know it, phone charger, and a warm layer.
  7. If you’re alone, message someone now to check in and, if possible, meet you at A&E or be available by phone.

What can wait

  • You do not need to figure out the cause right now.
  • You do not need to test yourself repeatedly (pinching, long walks, “see if it goes away”).
  • You do not need to decide about scans, surgery, or referrals—your job is to get assessed promptly.

Important reassurance

It’s common to feel embarrassed or unsure about these symptoms. You’re not wasting anyone’s time: new groin-area numbness or bladder/bowel control changes are treated as red-flag symptoms because delays can matter. Getting checked urgently is the safest choice even if the cause turns out to be something less serious.

Scope note

This guide covers first steps only to get you to the right level of urgent care and help you communicate symptoms clearly. Further decisions (tests, treatment, follow-up) come after you’ve been assessed.

Important note
