Prostatitis

Prostatitis is swelling or infection of the prostate. It's usually painful. The prostate is a small organ below the bladder that makes part of the semen fluid.

Prostatitis can cause urinary problems. You may have an urge to urinate often, burning pain, and a feeling that you can't empty your bladder. Symptoms may be sudden and severe (acute) or mild and long-lasting (chronic).
