The signs and symptoms vary depending on the various types of prostatitis.
Acute bacterial prostatitis: Category 1
Signs and symptoms of this form of prostatitis usually come on suddenly and may include:
Fever and chills
Flu-like symptoms
Pain in the prostate gland, lower back or groin
Urinary problems, including increased urinary urgency and frequency, difficulty or pain when urinating, inability to completely empty the bladder, and blood-tinged urine
Painful ejaculation
Acute prostatitis can be a serious condition and requires immediate medical treatment. See your doctor right away if you develop any of these signs and symptoms.
Chronic bacterial prostatitis: Category 2
The signs and symptoms of this type of prostatitis develop more slowly and usually aren't as severe as those of acute prostatitis. In addition, times when symptoms are better tend to alternate with times when symptoms are worse. Signs and symptoms of chronic bacterial prostatitis include:
A frequent and urgent need to urinate
Pain or a burning sensation when urinating (dysuria)
Pain in the pelvic area
Excessive urination during the night (nocturia)
Pain in the lower back and genital area
Difficulty starting to urinate, or diminished urine flow
Occasional blood in semen or in urine (hematuria)
Painful ejaculation
A slight fever
Recurring bladder infections
Chronic nonbacterial prostatitis: Category 3
The signs and symptoms of nonbacterial prostatitis are similar to those of chronic bacterial prostatitis, although you probably won't have a fever. The only way to determine whether prostatitis symptoms are caused by bacterial infection or are nonbacterial is through lab tests to find out whether bacteria is present in the urine or prostate gland fluid.
Other conditions
Prostatitis can be difficult to diagnose, in part because its signs and symptoms often resemble those of other conditions, such as bladder infections, bladder cancer or prostate enlargement due to benign or cancerous growth of the prostate.
