Everything You’ve Ever Wanted To Know About UTIs*

When you have a urinary tract infection, something feels very, very wrong down there. There’s a burning or stinging sensation when you pee, dull aching in your lower back, and in some cases you may be urinating blood.

If you’re a woman, odds are you’re going to have at least one in your lifetime, and middle-aged women are more likely to get the infection than men by a ratio of 30 to one. There are an estimated 150 million UTI cases around the world, according to the American Urological Association, and they cost about $6 billion to treat.
