FAQs: I have a white blister on my nipple and it hurts! What is this?

A blocked nipple pore, also called a bleb, occurs when skin overgrows a milk duct opening and milk backs up behind it. It usually shows up as a painful white blister on the nipple and the pain is localized. Milk blisters can be persistent and very painful during feeding, and it may take several days or weeks until the skin peels away and the affected area is healed.

Recommended Treatment:

  • Soak nipple in Epsom-salt solution (2 teaspoons of Epsom salt to 1 cup water), rinse, and apply moist heat. You can also use warm olive oil to help break the skin.
  • Nurse or pump immediately. Do breast compression while nursing/pumping to help push the milk forward.
  • Use gentle pressure at the base of the bleb after feeding/pumping and try to work it through the nipple pore opening.
  • In addition, it may be helpful to gently rub the blister area with a moist washcloth once a day.

If after several days, you don’t see any improvement, you may want to contact your health care provider; they may be able to use a sterile needle to open the blister. You also want to contact your doctor if you develop fever or the blister area is inflamed, red, swollen or oozing.
