Dysuria (Burning on Urination)
Dysuria (painful or difficult urination) is most commonly due to bacterial infection of the urinary tract causing inflammation of the bladder (cystitis) or kidney (pyelonephritis). In women, dysuria may also reflect inflammation of the vagina (vaginitis) or vulva (vulvitis). And in men, dysuria may be due to inflammation of the prostate (prostatitis) or the urethra (urethritis) from gonorrhea or chlamydia. There are many other causes of dysuria including irritation from chemicals in soaps, bubble baths, spermicides, and douches.
