What to do if…
you cannot pass urine and feel increasing discomfort

Short answer

If you cannot pass urine at all and your discomfort is increasing, go to A&E now. If you’re unsure where to go or need help arranging urgent care, use NHS 111 online or call 111; call 999 if you think it’s life-threatening or you cannot get to A&E safely.

Do not do these things

  • Do not keep forcing/straining to pee (it can worsen pain and doesn’t fix a blockage).
  • Do not “try to flush it through” by rapidly drinking lots of water.
  • Do not take someone else’s medication (including leftover antibiotics or painkillers) to “see if it helps”.
  • Do not try to insert anything into your urethra or attempt catheterisation yourself unless you have been specifically trained and told to do so for this situation.
  • Do not ignore this or try to sleep it off.

What to do now

  1. Go to A&E now if no urine is coming out and discomfort is building. This needs prompt assessment and treatment.
  2. Call 999 if you think it’s life-threatening or you can’t get to A&E safely, for example if you are collapsing/fainting, severely confused, or too unwell to travel.
  3. Do not delay leaving.
    • If it does not delay you, you may make one gentle attempt to pass urine (no straining), then stop.
    • Do not repeat attempts—focus on getting to urgent care.
  4. Bring (or note) details that help clinicians act quickly.
    • When you last passed urine; whether none has come out or only drops.
    • Any blood in urine, fever/rigors, back/flank pain, recent injury, recent surgery/anaesthetic, pregnancy/postpartum status.
    • A list/photos of all medicines (including recent changes), especially opioids, antihistamines, decongestants, antidepressants, and bladder/prostate medicines.
  5. If you already have a urinary catheter and it has stopped draining: treat it as urgent. Do not pull on it. Go to A&E.
  6. If you have new leg weakness, new numbness around the genitals/inner thighs (“saddle area”), or symptoms after a back injury: treat as an emergency—call 999 or go to A&E immediately.

What can wait

  • You do not need to work out the cause right now (prostate, infection, medication side effect, nerve issue, stone, etc.).
  • You do not need to decide on tests, referrals, or long-term treatment today—focus only on being assessed and safely relieved.
  • You do not need to “manage this at home” first.

Important reassurance

This situation is frightening and painful, and it’s common to worry you’re overreacting. You’re not: a sudden inability to pass urine with increasing discomfort is a recognised urgent problem, and getting prompt help is the right call.

Scope note

These are first steps only—aimed at getting you safely assessed and relieving the immediate problem. Follow-up and prevention depend on the cause and should be handled with a clinician.
