Pruritus vulvae is when someone (usually a woman) gets itchy around their private parts (their vagina). It can be very uncomfortable and make them want to scratch or rub the area, which can make it worse. This can happen for many reasons, like having an infection, wearing tight clothing, or using certain products like soap or lotion that are irritating. Sometimes it happens for no clear reason at all. If someone has pruritus vulvae, they should talk to a doctor to figure out why it's happening and how to make it go away.
