A blocked milk duct (also known as a plugged or clogged duct) happens during breastfeeding when one of the small tubes in your breast becomes blocked. This blockage prevents milk from flowing freely to your nipple. Your breasts have a whole network of these tubes, called mammary ducts, which carry milk from the breast tissue to the nipple. If something squeezes these tubes—like swelling in the surrounding tissue or blood vessels—the milk can back up. This usually creates a red, tender, and painful lump in the breast. It is important to treat it early to avoid a more serious infection.
The most obvious sign is a hard lump on your breast that feels sore or painful when you touch it. You might see redness over the area, or the lump may be large enough to see in the mirror. If you have ever felt engorged (when breasts are overfull), the lump feels very similar to that. Other symptoms include:
The main cause is inflammation (swelling) in the tissues and blood vessels around the duct. This can happen if:
Yes, it is possible. One common condition is called mammary duct ectasia. This happens when a milk duct widens and its walls thicken, leading to fluid buildup and blockage of the passage.
Most of the time, you can recognize and treat a blocked duct at home without seeing a doctor. If you are breastfeeding and feel a painful lump, it is probably a blocked duct. But if you feel like you have the flu, have a fever, or the pain is very strong, you should call your doctor. These could be signs of mastitis, which is an infection. Your doctor can check the lump to make sure everything is alright.
Most people can clear a clog in 2 days with home care. You should continue to breastfeed or pump as your baby needs, but do not pump more than usual, as over-pumping can cause more swelling. A simple way to remember treatment is the B.A.I.T. method:
You can also try very gentle stroking, as if you were petting a cat. Stroke from the lump toward your collarbone or armpits. This helps move extra fluid into your lymphatic system.
The best sign is that the hard lump has disappeared. If you are pumping, you might also see a thick, fatty string or glob of milk come out; this is usually the "plug" that was causing the blockage.
Yes, they can come back. Sometimes a lump gets smaller and seems to go away, but it can fill up again a few hours later. Some people are just more likely to get clogs than others.
If you leave a blocked duct untreated, it can turn into mastitis (a breast infection). Mastitis symptoms usually come on very quickly and include:
Yes. You should continue to nurse as much as your baby needs. Keeping the milk moving is important for recovery.
The most important thing is to ensure your breasts are drained during feedings. You can tell a breast is drained if:
Other prevention tips include:
If you are weaning, do it slowly. Only pump or extract enough milk to feel comfortable. This tells your body to slow down production without causing a clog.
You should contact your doctor if the lump does not go away after a few days of home treatment. You should also call them immediately if you see signs of mastitis, such as:
