I Told the Doctor My Nipples Were Itchy. And Here's What He Told Me!
Olive oil massage
Massaging olive oil onto nipples has also showed to be effective, due to the oil's moisturizing abilities. Simply apply and massage gently, and wash afterward. Or, if you're looking to pamper yourself a bit, you can massage the olive oil onto the nipples before taking a bath.
Speaking of baths, avoid hot showers at all costs. They can make your skin drier, which heightens itchiness. Cold water is best when cleansing the nipples.
