(HealthDay News) - Pain while urinating often indicates an infection -- usually in the urinary tract. However, it can also be caused by other conditions, and should always be diagnosed and treated by a doctor.

Here are possible causes of painful urination, courtesy of the U.S. National Library of Medicine:

• A urinary tract infection (UTI).
• Gonorrhea or chlamydia, both of which can cause inflammation of the urethra.
• An inflamed prostate.
• Chronic inflammation of the wall of the bladder.
• Inflammation of the vagina.
• Inflammation of the vulva.
