Prostatitis

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

Prostatitis can cause urinary problems, such as 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).
