This type of blister may sometimes be red or brown, or a “blood blister.” For this type of blister, the problem is nipple damage due to friction, rather than a milk duct opening being blocked and requires correcting an ineffective latch and or proper flange fitting. This is NOT the same as a blister on the nipple caused by friction. Reducing saturated fats can help to prevent the recurrence of this type of obstruction.īoth of these types of milk duct obstructions are associated with recurrent mastitis.Ī completely different type of blister is caused by friction from a baby’s improper latch or sucking or from the use of a badly fitting nipple shield or flange. This second type can often be manually expressed from the milk duct. The blockage may be a tiny, dry clump of hardened milk or a “string” of fattier, semi-solidified milk. This type of milk blister often pops out from the pressure of nursing or milk expression but oftentimes it has to be gently exfoliated from the surface of the milk duct because of the pain it causes.Ī second type of milk blister appearing as a white spot on the nipple may be caused by a blockage within the milk duct, as opposed to the skin covering the milk duct. Milk blisters can be persistent and very painful during feeding/pumping and may remain for several days or weeks and then spontaneously heal when the skin peels away from the affected area. If you compress the breast /chest so that milk is forced down the ducts, the blister will typically bulge outward. A milk blister, or blocked nipple pore, happens when a tiny bit of skin overgrows and clogs a milk duct opening causing milk to back up It usually shows up as a painful white, clear or yellow dot on the nipple or areola, and the pain tends to be focused at that spot and just behind it.
