Urethritis: the burning pee and discharge that needs the sexual-health clinic
Last updated September 3, 2026.
Urethritis is inflammation of the urethra (the urine tube): causing burning or pain on urination, discharge from the tip of the penis, and itching or irritation at the opening. In men it is mostly sexually transmitted (the chlamydia and the gonorrhea kinds, plus the non-specific kind), it is diagnosed by the swabs and the urine test at the sexual-health clinic (confidential, free, genuinely routine), and it is cured by the antibiotic course, with the partners tested too.
What does it feel like?
The urinary burning (the peeing-through-broken-glass of the classic description), the discharge (the clear-to-cloudy-to-yellow drip from the tip, often noticed on the morning underwear), the itch or irritation at the opening, and the frequent urge. It appears days to a few weeks after the sexual exposure, it overlaps the ordinary urine infection (and in men the urinary symptoms are urethritis until proven otherwise: the male UTI is uncommon), and in women it hides under the cystitis label. The asymptomatic male versions exist (the discharge never noticed), which is why the partner testing matters.
Why does it happen?
The infection kinds: the gonorrhea (the classic purulent discharge), the chlamydia (the milder, commoner, often silent), and the non-gonococcal kind (the mycoplasma, the trichomonas, the adenovirus, and the genuinely-unnamed), spread by the unprotected sex. The non-infection kinds (the irritants, the friction, the catheter) are the minority. The sexual-health clinic sorts it with the urine sample and the swabs: genuinely painless these days, genuinely confidential, and the results steer the exact antibiotic.
How is it treated?
- The testing first: the urine sample and the swabs at the sexual-health clinic (or the GP): the gonorrhea, the chlamydia, and the others tested together.
- The antibiotics: the specific course for the found bug (often given the same day, on the story, while the results bake): genuinely curative.
- The partner testing and treating: the partners need the testing (and often the treatment) before the sex resumes: the ping-pong infection is the untreated partner.
- The no-sex rule until cleared: the week after the treatment (or until the partners are treated too).
- The retest in the persistent: the symptoms hanging on get the re-swab (the resistant bugs and the missed partners are the usual answers).
When is it urgent?
Urethritis is clinic medicine (the sexual-health clinics take walk-ins); the urgent items: the severe pain with fever and the feeling unwell, the testicular pain or swelling joining (the epididymitis: promptly), and the inability to pass urine. The ordinary burning-and-discharge is the this-week clinic visit, and the untreated course risks the spread to the testicles and the partners. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Could this just be a urine infection?
In men, almost never the answer: the ordinary bladder infection (the cystitis of women) is uncommon in young men (the long male urethra protects), so the male urinary burning, especially with the discharge, is urethritis until proven otherwise (and in the three-weeks-after-sex context, the sexually-transmitted kind until proven otherwise), which is why the sexual-health clinic and its swabs, not the UTI antibiotic guess, is the right door. The women's version hides differently (the urethritis and the cystitis genuinely overlap: the burning, the frequency), and the persistent or post-sex cystitis in women earns the STI testing too. The discharge is the giveaway either way: the urine infections do not produce it, and your cloudy discharge is the symptom that books the clinic.
Which infection is it likely to be?
The likely shortlist, and why the testing beats the guessing: the chlamydia (the commonest: often the milder, cloudier discharge, sometimes no symptoms at all, cured by the short antibiotic course), the gonorrhea (the classic: the yellower, heavier discharge, the stronger burning, also cured but needing the test-of-cure because the resistance is genuinely rising), and the non-gonococcal others (the mycoplasma, the trichomonas, the adenovirus: the genuine alternatives the swabs test for). The look of the discharge does not identify the bug (the overlapping appearances), the timing suggests (the chlamydia's slower two-to-three-week onset fits yours), and the clinic tests for all of them from the same sample. The guesswork era is over: the results name it, and the named bug gets its exact antibiotic.
What actually happens at the sexual-health clinic?
The demystifying, because the embarrassment is the whole barrier: the clinics are free, confidential (separate from your GP record unless you ask otherwise), walk-in or bookable, and genuinely routine (the staff see your story constantly and judge nothing). The process: the history (the symptoms, the exposures: brief and professional), the testing (the urine sample: the first-catch kind, plus the swabs: the self-taken options now common, the blood test for the HIV and syphilis offered with it: say yes, it is one arm), and often the treatment the same day on the story (the antibiotics before the results when the picture is clear). The results come by text in days. The whole visit is under an hour, and the burning resolves within days of the antibiotics. The door is much less frightening than the hallway worrying.
Does my partner need to know?
Yes, genuinely, and it is kinder than it feels: the partner needs testing (and usually treatment) because the untreated partner re-infects you (the ping-pong: your cure undone in one encounter), because the infections harm silently (the chlamydia's silent damage to the women's fertility is the genuine stakes), and because the telling is routine (the sentence is short: I have tested positive for an infection and you need a test too). The clinics carry the load: the partner-notification service (the anonymous text or call from the clinic, naming no names) exists for exactly the conversations you cannot have, and it is genuinely used constantly. The no-sex rule holds until both are treated. The partner who matters will thank you; the clinic handles the rest.
What happens if I leave it untreated?
The reasons the clinic visit is tomorrow and not someday: in men the untreated urethritis ascends (the epididymitis: the testicle inflaming, painful, swollen: the fertility-threatening complication, and the reason the testicular pain is the urgent flag), the prostatitis, and the rare reactive arthritis (the joints, the eyes, and the urethra inflaming together), while the infection keeps transmitting (every unprotected encounter passes it), and the discharge continues. In the untreated partners the stakes run higher (the pelvic inflammatory disease and the fertility damage, silently). The antibiotic course prevents all of it and takes days: the calculus is genuinely one-sided, and the four days you have waited have already been four days of transmission risk. The embarrassment costs more than the visit.
How do I avoid this next time?
The practical protection, genuinely effective: the condoms for the new and the casual partners (genuinely protective against the whole STI list, and the habit that makes the testing intervals longer), the testing routine (the sexual-health screen with every new partner or at the regular intervals: the three-monthly for the higher-turnover, the yearly for the steady: genuinely free and quick), the mutual testing before the condoms come off (the conversation that is genuinely easier than the urethritis), and the symptoms prompt-visit rule (the four-day wait you just did: shorten it next time). The new-partner sex you had is the ordinary human behavior; the system that keeps it safe is the testing rhythm plus the condoms, and the clinic you visit tomorrow is exactly the place to set that up. Most people learn this lesson once.
