Urinary Track Infection or UTI is quite commonly seen in most male as well as female. The symptoms of UTI are: Pain or a burning feeling during urination, a feeling of urgency, or feeling the need to urinate frequently, an altered appearance of the urine, either bloody (red) or cloudy (containing pus), pain or pressure in the rectum (men) or in the area of the pubic bone (women), passing only a tiny amount of urine even when the urge to urinate is strong. I would like to know what are the causes of urinary track infection?
