Vaginitis is inflammation of the vagina. It's due to an imbalance of yeast and bacteria that normally live in the vagina.
Along with discomfort, you may notice a smell that's different than usual. You could have an infection caused by bacteria, yeast, or viruses.
Chemicals in soaps, sprays, or even clothing that come in contact with this area could be irritating the delicate skin and tissues.It's not always easy to figure out what's going on, though.
You'll probably need your doctor's help to sort it out and choose the right treatment.
