Lots of things can make your nipples itchy. They’re sensitive in general. They also stick out, and they can get irritated from friction, eczema, breastfeeding, or pregnancy. Rarely, itchy nipples can be a sign of a more serious condition. Even if your urge to scratch is great, the problem is usually easy to treat. If you’ve been using over-the-counter products for a couple of weeks and the itch isn’t gone, check with your doctor.
