Types and Causes
Physicians recognize four forms of prostatitis:- Acute bacterial prostatitis: A sudden infection, usually from bacteria ascending the urinary tract, causing fever and marked urinary symptoms. It is uncommon but serious.
- Chronic bacterial prostatitis: A low-grade infection that lingers in the prostate and causes repeated urinary tract infections with the same organism.
- Chronic prostatitis / chronic pelvic pain syndrome (CPPS): The most common form - persistent pelvic pain and urinary symptoms without demonstrable infection, likely involving nerve sensitization and pelvic floor muscle tension.
- Asymptomatic inflammatory prostatitis: Inflammation found incidentally during testing for other conditions; it needs no treatment.
Symptoms
Symptoms vary by type but commonly include:- Pain: Aching in the perineum (the area between the scrotum and rectum), lower abdomen, low back, or genitals; ejaculation may be painful.
- Urinary symptoms: Burning, frequency, urgency, a weak stream, or a sense of incomplete emptying.
- Flu-like illness: In acute bacterial prostatitis, fever, chills, and body aches come on quickly.
- Sexual symptoms: Discomfort during or after ejaculation, reduced desire, and occasionally blood in the semen - alarming to see, but usually from inflammation rather than anything sinister.
Diagnosis
Evaluation includes a review of your symptoms, a physical exam with a gentle digital rectal exam of the prostate, and urine testing with culture to identify bacteria. Your physician will also distinguish prostatitis from look-alike conditions: an enlarged prostate (benign prostatic hyperplasia) causes similar urinary symptoms without pain, while pain radiating from the flank toward the groin suggests kidney stones instead. A PSA blood test, if drawn during prostatitis, is often temporarily elevated and should be rechecked after treatment.Treatment
Treatment depends on the type:- Antibiotics: Bacterial prostatitis is treated with antibiotics that penetrate prostate tissue well, such as trimethoprim-sulfamethoxazole or ciprofloxacin - typically for two to four weeks in acute cases and longer courses for chronic bacterial infection. Finishing the full course is essential to prevent relapse.
- Alpha-blockers: Medications such as tamsulosin relax muscle at the bladder outlet, easing urinary symptoms.
- Anti-inflammatories and comfort measures: NSAIDs, warm sitz baths, and avoiding prolonged cycling can reduce pain.
- Chronic pelvic pain syndrome: Improves most with a combination approach - pelvic floor physical therapy, stress management, and medication tailored to symptoms - rather than repeated antibiotics.
Complications
Most men recover fully, but untreated bacterial prostatitis can lead to:- Urinary retention: A swollen prostate can block urine flow entirely, sometimes requiring a temporary catheter.
- Prostate abscess: A walled-off pocket of infection that fails to clear with antibiotics alone and may need drainage.
- Bloodstream infection: Bacteria can spread from the prostate into the blood and cause serious systemic illness, which is why fever with pelvic pain is treated urgently.
- Epididymitis: Infection spreading to the coiled tube behind the testicle, causing scrotal pain and swelling.
When to Seek Immediate Care
High fever with pelvic pain, or the inability to urinate at all, requires same-day medical attention - acute bacterial prostatitis can progress quickly. Pelvic pain that lingers is not something to tough out.

Prostatitis is often treated with the wrong antibiotic for too short a time, or with antibiotics when there is no infection at all. Knowing which form you have, and what each form actually responds to, avoids months of pelvic pain and several needless prescriptions.
Why the antibiotic and the course length matter
The prostate lets few antibiotics in. Ciprofloxacin, levofloxacin, and trimethoprim-sulfamethoxazole reach it in useful concentrations; cephalexin and nitrofurantoin, common choices for a bladder infection, largely do not, which is why a course that cleared the urine leaves the prostate infected and the urinary tract infection keeps returning. Fluoroquinolones carry a risk of tendon rupture that rises after 60 and with steroid use, so a sudden ache in the heel or shoulder means stopping and calling. In sexually active younger men, chlamydia and gonorrhea are tested for, since they need doxycycline or a different regimen. Chronic bacterial prostatitis is confirmed cleared with a repeat culture after treatment, not by how you feel.
Chronic pelvic pain is treated by symptom, not by more antibiotics
Once cultures are negative, further antibiotic courses do not help. Treatment is matched to the symptoms present: tamsulosin or alfuzosin for a weak stream and urgency, ibuprofen or another anti-inflammatory in short courses for pain, and pelvic floor physical therapy for the muscle tension found in most men with this form. Nerve-pain medicines and stress treatment are added when pain dominates; our chronic pain without opioids article covers the approach.
What quietly keeps it going
Prolonged sitting, a narrow bicycle seat, chronic constipation, holding urine, and, for some men, caffeine, alcohol, and spicy food all aggravate pelvic symptoms. Dehydration in the Florida heat concentrates the urine and irritates the bladder, so fluids are kept up through the day and tapered in the evening.
PSA, an enlarged prostate, and cancer
A PSA drawn during prostatitis is commonly elevated and is repeated six to eight weeks after treatment before any conclusion is drawn; the elevated PSA page explains the follow-up. After 50, benign prostatic hyperplasia and prostatitis frequently coexist, and our prostatitis, BPH, and prostate cancer article sets out how they are told apart. Pain with ejaculation and reduced desire are common in chronic prostatitis and usually improve as it is treated; persistent erectile dysfunction is evaluated on its own.
When a urologist is needed, and when it is an emergency
Being unable to pass urine, fever with pelvic pain, or worsening despite antibiotics needs same-day care, and an abscess is looked for with imaging when fever does not settle within a couple of days of treatment. Infection that returns after two properly chosen courses, blood in the urine, or symptoms in a man with prior prostate procedures is referred to urology, and our genito-urinary team coordinates that referral. The NIDDK and MedlinePlus publish patient guidance on prostatitis and other prostate problems.
If pelvic pain or urinary symptoms have lasted more than a few weeks, or antibiotics keep being prescribed without a culture, schedule a visit.
