@Mountaindewed, it is possible that underwear could be a factor in UTIs. I wouldn't wear too tight of underwear. Also, always go for cotton ones, or at least ones that have a cotton crotch. Also, not too tight of pants. It's also possible the UTI could be partly stress-induced. Stress brings on all kinds of things.

Though perhaps a little bit of an old-fashioned home remedy, in addition to prescribed treatment, having a UTI is a good excuse to enjoy some cranberry juice cocktail. Cranberry juice is known to be helpful at curbing them. And tastes good.
