Acute prostatitis
Acute prostatitis is a serious bacterial infection of the prostate gland. 
Acute prostatitis is most commonly caused by urinary tract infection which is not timely cured. The acute prostatitis may also caused by acute infections of skin, tonsils, dental caries, intestinal tract or respiratory tract. The bacteria can reach the prostate gland via blood, causing inflammation of the prostate gland. 
Men with acute prostatitis often have chills, fever, fatigue, pain in the lower back and genital area, urinary frequency and urgency often at night, burning or painful urination, body aches, and a demonstrable infection of the urinary tract, as evidenced by white blood cells and bacteria in the urine.
A urine test will usually detect bacteria if you have acute prostatitis. Other tests such as X-rays or scans may be advised following acute prostatitis. This is to rule out any problem with your urinary tract that may have contributed to causing the infection.
A four-week course of antibiotics is needed. Four weeks of antibiotics are thought to be necessary to reduce the chance that you develop chronic (persistent) prostatitis. Another treatment is herbal medicine Diuretic and Anti-inflammatory Pill.
