A clogged duct can feel like a painful lump under the skin, and it often sneaks up when you’re least expecting it. If you’re breastfeeding or pumping, you’re probably familiar with the discomfort—and frustration—that can come with one. Here’s what you can do to find relief and get milk flowing freely again:

What is a Clogged Milk Duct?

It’s a blockage in one of the milk ducts that carries milk from deep in your breast to the nipple. You might feel a tender, hard lump, experience swelling or redness, and sometimes even a slight fever if it’s been clogged for a while.

What Causes It?

Missed feedings or long stretches between sessions
Poor latch or ineffective milk removal
Tight clothing or pressure on the breast
Stress or fatigue (yes, really—your body keeps score)

How to Treat a Clogged Duct:

Keep Nursing or Pumping-
Don’t stop! Frequent milk removal is the #1 way to unclog a duct. Begin with the affected side to encourage strong letdown.
Massage Gently (but firmly)-
Use your fingers to apply pressure behind the lump and massage toward the nipple during and between feedings.
Apply Heat-
Use a warm compress or take a warm shower before feeding or pumping to help open things up.
Change Positions-
Try different nursing positions to fully drain the breast. Some find the “dangle feeding” position (where baby feeds while you lean over them) super effective.
Stay Hydrated and Rested-
Your body needs both to function well—especially during times of stress or illness.
Use Lecithin (if needed)-
Some people find sunflower lecithin (a supplement) helps prevent clogs by thinning milk. Talk to your healthcare provider first.

When to Call for Help:

If your symptoms don’t improve after 24–48 hours, or you develop a fever, chills, or flu-like symptoms, it could be mastitis (an infection). Don’t wait—call your doctor or lactation consultant.

You’re Not Alone

Clogged ducts are common—but that doesn’t mean you have to suffer through them. Be gentle with yourself, ask for help, and remember this phase will pass.

You’ve got this.
