What exactly is a clogged milk duct and how does it differ from other breast-related conditions, such as mastitis? A clogged milk duct, also referred to as a blocked or plugged duct, is when milk is blocked in the breast, resulting in incomplete drainage of the milk duct. This causes a tender lump to form in the breast and can lead to discomfort in that specific area.1
Common symptoms of a clogged breast duct include: 2
- Pain in the one area of the breast
- A tender lump in one area of the breast
- Only a slight increase in warmth of the affected area
- A small white blister on the nipple
In short, a clogged duct is when there is a localized, uncomfortable lump on the breast, without any other sign of illness or fever. If there are fever or flu-like symptoms and if the breasts are warm to the touch, it could be mastitis. Find more information about mastitis symptoms and support here.
