Quick answer. Painful or burning urination (dysuria) is most commonly caused by a urinary tract infection. See a doctor promptly, and seek urgent care if you also have fever, back or flank pain, or blood in your urine, or if you are pregnant or male.
Pain, stinging or a burning feeling when you pass urine is called dysuria. It is most often due to a urinary tract infection, but it can also point to other conditions that need assessment.
This guide covers the usual causes, the red flags that mean you should be seen urgently, and which specialist to see in Singapore.
At a glance
| Possible cause | What it suggests | Urgency |
|---|---|---|
| Urinary tract infection (cystitis) | Burning, urgency, frequency, cloudy urine | See a doctor soon |
| Kidney infection (pyelonephritis) | Painful urination plus fever and back/flank pain | Urgent – see a doctor or A&E |
| Sexually transmitted infection | Burning with discharge or pelvic discomfort | See a doctor soon for testing |
| Bladder or urethral irritation | Discomfort from products, dehydration or stones | Non-urgent unless severe or persistent |
| Painful urination in men or pregnancy | Higher risk of complications | Prompt medical review needed |
Red flags: when to see a doctor urgently
Get urgent medical care if painful urination comes with any of these signs that the infection may be spreading or serious:
- Fever, chills or shivering — the infection may have reached the kidneys.
- Pain in your back or side (flank), just under the ribs.
- Blood in the urine (pink, red or brown).
- Feeling very unwell, confused or unable to keep fluids down.
Painful urination during pregnancy, or in men, should be reviewed promptly because complications are more likely. In a medical emergency in Singapore, call 995 or go to your nearest A&E.
The most common cause: urinary tract infection
Most painful urination is caused by a urinary tract infection (UTI). A bladder infection (cystitis) typically causes a burning sensation when passing urine, a frequent and urgent need to go, passing only small amounts, and cloudy or strong-smelling urine. UTIs are very common in women but can affect anyone. Many uncomplicated UTIs are treated effectively with a short course of antibiotics.
Other causes to consider
Painful urination can also be due to sexually transmitted infections (often with discharge), irritation from soaps or hygiene products, dehydration, kidney or bladder stones, or in men, prostate inflammation. Because the causes overlap, a urine test usually helps identify what is going on.
How painful urination is diagnosed
A doctor will ask about your symptoms and examine you, and usually test a urine sample to look for infection. Depending on your history, swabs for sexually transmitted infections, blood tests, or imaging such as an ultrasound may be arranged. Recurrent or unusual cases, and most cases in men, are investigated more thoroughly.
Which specialist should you see?
A GP or polyclinic can diagnose and treat most cases of painful urination. If symptoms are recurrent, severe, occur in men, or do not settle with treatment, you may be referred to a urologist for further assessment.

When to seek help sooner rather than later
See a doctor early rather than waiting it out, especially if you have fever, back pain, blood in the urine, are pregnant, or are male. Treating a UTI promptly reduces the risk of it spreading to the kidneys.
What to expect at the appointment
Your doctor will ask about your symptoms: the burning or stinging, how often and how urgently you need to pass urine, whether the urine is cloudy, bloody or strong-smelling, and whether you have fever, back pain or any discharge. They will usually test a urine sample to check for infection. Depending on your history, swabs for sexually transmitted infections, blood tests, or imaging such as an ultrasound may be arranged. Most uncomplicated urinary tract infections are treated with a short course of antibiotics, and it is important to complete the course as prescribed.
How to prepare
Before your visit, note when the symptoms began, whether you have had similar episodes before, and any associated features such as fever, back or flank pain, or blood in the urine. Mention if you are pregnant or could be, as this affects treatment choices. It can help to avoid passing urine for an hour or so before your appointment if you are asked to provide a sample, and to follow any instructions on giving a clean midstream sample.
Self-management at home
For a mild, uncomplicated bladder infection without warning signs, drinking plenty of water to flush the bladder and using simple pain relief such as paracetamol can ease discomfort while you arrange to be seen. Avoid holding urine for long periods. Good general habits, staying well hydrated and not delaying passing urine, may reduce recurrences in those prone to infections. Self-care does not replace treatment: see a doctor if symptoms persist beyond a day or two, recur often, or you develop any red flag such as fever, back pain or blood in the urine.
Special situations
Painful urination in men, in pregnancy, in young children, or in people with diabetes or a weakened immune system should be reviewed promptly, as complications are more likely and the cause may differ. Recurrent infections, or symptoms that do not settle with treatment, usually warrant further assessment and may be referred to a urologist. Fever with back or flank pain suggests the infection may have reached the kidneys and needs urgent care.
Common questions
Can a urinary tract infection clear up on its own?
Some very mild bladder infections settle with fluids and time, but many need antibiotics. Because untreated infection can spread to the kidneys, it is safer to see a doctor, especially if you have any warning sign.
Why is painful urination treated more cautiously in men?
Urinary infections are less common in men and can be linked to other conditions such as the prostate, so they are usually investigated more thoroughly rather than treated as simple cystitis.
