Key takeaways
Prostatitis is not one disease. It is four very different conditions grouped under one name, and only one of them is an emergency.
Acute bacterial prostatitis with fever, chills or an inability to pass urine is a medical emergency. Go to A&E or call 1669.
The most common type, chronic pelvic pain syndrome, is not an infection and does not respond to antibiotics. Repeated courses often do more harm than good.
Getting the diagnosis right matters. A proper workup separates a true infection from an STI, from bladder problems, and from pelvic pain.
Chronic pelvic pain syndrome is usually managed rather than cured, but most men improve with the right combination of treatments.
01
What prostatitis is & the four types
Prostatitis means inflammation or irritation of the prostate, the walnut-sized gland below the bladder that surrounds the urethra. But the word is used for several conditions that feel similar yet have very different causes and treatments.
Doctors separate them using the NIH classification.¹ Most men who are told they have prostatitis do not have a bacterial infection at all. The great majority have chronic pelvic pain syndrome, where no infection can be found.
Getting the category right changes everything. An antibiotic that clears one type is useless, and potentially harmful, for another. That is why testing, rather than guessing from symptoms, is the important first step.
The symptoms overlap: pain in the pelvis, perineum or lower back, burning or urgency when passing urine, and discomfort during or after ejaculation. Because they overlap so much, only a proper workup can tell the types apart.
Acute bacterial (rare)
A sudden bacterial infection with fever, chills and painful urination. This is a medical emergency and needs urgent care, not a clinic appointment days later.
Chronic bacterial
The same bacteria causing relapsing urinary infections over months. Confirmed by culture and treated with a long, targeted antibiotic course.
Chronic pelvic pain (CPPS)
Around 9 in 10 cases. Persistent pelvic pain and urinary symptoms with no infection found. It is managed, not cured with antibiotics.
Asymptomatic inflammation
Inflammation found by chance, often during a fertility or PSA check, with no symptoms at all. It usually needs no treatment.
02
Getting diagnosed properly in Bangkok
Why it is over-diagnosed
Prostatitis is often diagnosed on symptoms alone and treated with repeat antibiotic courses. Because 9 in 10 cases are not bacterial,¹ those courses rarely help and can drive antibiotic resistance, a growing problem in Thailand.
What a proper workup looks like
A digital rectal exam, a urine dip and culture, and where relevant an STI screen and a post-massage urine test. The aim is to confirm which type you have before any antibiotic is prescribed.
When it is actually an STI
Burning, discharge or a recent new partner can point to chlamydia or gonorrhoea rather than prostatitis. These need different tests and treatment, so an honest sexual history matters. Everything stays confidential.
An honest note. Chronic pelvic pain syndrome is usually managed rather than cured. Most men improve with the right combination of treatments, but it can take patience and more than one approach.
03
What the evidence says about treatment
For chronic bacterial prostatitis the evidence is clear. A 4 to 6 week course of a fluoroquinolone antibiotic such as ciprofloxacin or levofloxacin clears the infection in most men once a culture has confirmed the bacteria.² Shorter courses relapse more often, which is why finishing the full course matters.
Chronic pelvic pain syndrome is harder. Large trials show that antibiotics and alpha-blockers used alone perform little better than placebo.⁴ ⁵ What does help is a combined, individualised approach: pelvic floor physiotherapy, pain management, treating bladder symptoms, and addressing stress, guided by each man's specific symptom pattern.
This is why phenotype-directed care is now standard. Studies using this tailored method report meaningful improvement in around three in four men,⁷ though it takes time and often more than one treatment before the right mix is found.

Red flags & what we check
Fever + retention = hospital now
A high fever with chills, feeling very unwell, or being unable to pass urine can mean acute bacterial prostatitis or sepsis. Go to A&E or call 1669 straight away. Do not wait for an appointment.
Exam and urine testing
We start with a digital rectal exam and a urine dip and culture. This confirms whether bacteria are actually present and guides whether an antibiotic is even appropriate.
STI testing, when relevant
If your history suggests it, we screen for chlamydia and gonorrhoea, because these are treated very differently from prostatitis. Testing is confidential.
PSA and imaging caveats
Prostatitis inflames the prostate and can raise PSA, so a PSA test taken during or soon after inflammation can mislead. We time it carefully. Imaging is rarely needed unless an abscess or another cause is suspected.

Get a straight answer about your symptoms.
Start on WhatsApp or LINE
Message our team with what you are experiencing. It is confidential and PDPA-protected, and there is no pressure to book.
A focused 15-minute consult
A licensed Thai physician reviews your symptoms and history in a focused 15-minute consultation, in clinic at Phrom Phong or as a first chat.
Targeted testing
If needed, we run a urine culture, STI screen and exam to confirm which type of prostatitis you have, rather than guessing from symptoms.
A plan that fits your type
Antibiotics only where a culture confirms bacteria; a tailored, multimodal plan for chronic pelvic pain. We follow up, tracking your symptoms with a validated score,⁶ to see what is working.
No guessing, no blanket antibiotics. Any treatment follows testing and a doctor's assessment. If prostatitis is not the cause, we will look for what is.

“Most men I see have already taken three or four rounds of antibiotics that were never going to work, because their prostatitis was never an infection. Testing first, then treating the right cause, is how men actually get better.”

Frequently asked questions
Is prostatitis an STI?
Usually not. Most prostatitis, especially chronic pelvic pain syndrome, is not sexually transmitted. But burning or discharge can point to an STI such as chlamydia or gonorrhoea, which is why testing matters when your history suggests it.
Will antibiotics cure my prostatitis?
Only if a culture confirms bacteria. Around 9 in 10 cases are chronic pelvic pain syndrome, which is not an infection and does not respond to antibiotics. Repeated courses in that situation rarely help and can cause harm.
When is prostatitis an emergency?
A high fever with chills, feeling very unwell, or being unable to pass urine can signal acute bacterial prostatitis or sepsis. This needs urgent care. Go to A&E or call 1669.
How is prostatitis diagnosed?
With an exam, a urine dip and culture, and where relevant an STI screen and a post-massage urine test. The point is to confirm which of the four types you have before deciding on any treatment.
Can prostatitis be cured?
Bacterial types can usually be cleared with the right antibiotic course. Chronic pelvic pain syndrome is generally managed rather than cured, though most men improve with a tailored plan over time.
How long does treatment take?
Confirmed chronic bacterial prostatitis usually needs a 4 to 6 week antibiotic course. Chronic pelvic pain syndrome takes longer and often needs several approaches together, so improvement is measured over months.
Is prostatitis the same as an enlarged prostate?
No. An enlarged prostate (BPH) is age-related growth that mainly affects urine flow, without the pain of prostatitis. They can feel similar, so an assessment helps tell them apart.
Does prostatitis raise my PSA?
Yes, inflammation can temporarily raise PSA, so a test taken during or soon after prostatitis can be misleading. We time PSA testing carefully and repeat it once the inflammation settles.
