White spot from a blocked milk duct

A small white or pale dot at the nipple opening may be a thin layer of dried milk or milk held behind a narrowed duct opening. The area can feel tender, and a firm or sore patch may develop deeper in the breast. Pressure from a tight bra, changes in feeding frequency, or shallow attachment can contribute. Breast pain is a common presentation of a blocked milk duct, but not every nipple spot has the same cause; irritation, a blister, or infection can look similar.

Continue breastfeeding or expressing according to your baby’s needs, focusing on a comfortable latch rather than forceful emptying. Use gentle breast massage toward the nipple only if it feels soothing, and try a cool pack after feeds for swelling. Avoid piercing, squeezing, or repeatedly scraping the white spot, which can injure the skin. A lactation consultation can help check positioning, pump settings, and feeding patterns. Rest, fluids, and a supportive bra may also help.

Arrange prompt medical advice if you develop fever, chills, flu-like feelings, spreading redness, increasing warmth, severe breast pain, pus, or a lump that does not improve. Seek review if the white area keeps returning or the nipple skin breaks. Do not stop feeding solely because of a blocked duct unless a clinician gives a specific reason.

Ask whether the spot looks like a milk blister, irritation, or infection, and whether your latch needs assessment. Discuss pain relief compatible with breastfeeding, signs of mastitis, and when persistent symptoms need imaging or another examination.
