Breast-Feeding Problems: Plugged Ducts

What is a plugged duct?

A plugged duct is when one or more of the milk ducts become blocked. It will feel like a hard, tender lump in your breast. Plugged ducts are usually caused by incomplete emptying of the breast. A plugged duct can also be caused by stress, fatigue, or a tight bra. Some women are more prone to plugged ducts than others.

Because a plugged duct can lead to a breast infection, it needs to be unplugged as soon as possible.

How can I unplug the duct?

  • Nurse on the tender side first when the baby is hungriest and sucks more strongly. This will ensure complete emptying of that breast.
  • Massage the breast with the lump, expressing extra milk and trying to unplug the duct.
  • Between nursing sessions apply moist heat to the breast. (The best way is to soak in a hot bath while massaging your breast and expressing milk. A hot shower or a heating pad is also helpful.)
  • Be persistent! With a plugged duct you have to work with massage, expression, nursing, and moist heat until it clears.
  • Sleep on your side instead of your back to assist the flow of milk down the ducts in your breasts.
  • Since stress can be an important factor in plugged ducts, make sure you get plenty of rest and relaxation.
  • When the plugged duct unclogs, you may feel a burning or pinching.

WARNING: If a plugged duct is accompanied by redness, a painful lump, and/or a fever and flu-like feeling, you could have a breast infection. Call your physician immediately!

How can I prevent plugged ducts?

  • Nurse frequently.
  • Empty each breast at each nursing.
  • Avoid tight or poorly fitting bras.
  • Sleep on your side instead of back.
  • Get plenty of rest.
