A white spot on the nipple may also be called a blocked nipple pore, a bleb or a milk blister. It is usually about the size of a pinhead or a bit larger.
The 'white' spot may not be white in colour. It may be more of a pink or light yellow colour. The skin around the white spot may be red and inflamed.
A white spot can appear at any stage of breastfeeding and may come and go. It usually feels sore throughout a feed.
What causes the white spot?
Scientists think white spot is caused by a blocked duct at the end of the nipple or because of skin growing over the opening of the duct.
Treating white spot
Sometimes the thin layer of skin over the white spot can burst or the thickened milk can move while your baby is feeding.
Try soaking your nipple in warm water and then gently rubbing it with a wet face-washer. This may need to be done daily if the white spot keeps coming back.
Olive oil massaged into the affected nipple may also help soften and break up the blockage.
If the soaking or massage doesn't help to remove the white spot, see your doctor. They might decide to use a sterile needle to gently release the blockage. It is important that this is not done too frequently as the skin may become scarred.
When the white spot goes, it’s usually an instant relief.
If the white spot is causing pain, try to focus on your baby's attachment to the breast. Change feeding positions to avoid pressure on the sore spot if necessary.
See your doctor if your white spot doesn't go away.
