Quick Answer
A clogged milk duct usually feels like a firm, tender lump in the breast. It may cause localized pain, swelling, or discomfort that worsens before feeding and improves afterward.
Why It Happens
Clogged ducts occur when milk flow is blocked or slowed. Common reasons include:
- Incomplete breast emptying during feeds
- Pressure from tight clothing or bras
- Skipped or irregular feeding sessions
- Changes in feeding patterns or weaning
- Stress or fatigue affecting milk letdown
What It Feels Like
- A small, hard lump or wedge-shaped area in the breast
- Tenderness or soreness in one spot
- Localized swelling or warmth
- Discomfort that lessens after feeding or pumping
- Occasional white spot on the nipple (milk bleb)
- No systemic symptoms — unlike mastitis, clogged ducts usually do not cause fever or flu-like feelings
What Parents Can Try
- Breastfeed or pump frequently to keep milk flowing
- Ensure a deep latch for effective milk removal
- Massage gently toward the nipple during feeds
- Apply warm compresses before feeding to encourage letdown
- Use different breastfeeding positions to drain all areas of the breast
- Wear supportive but non-restrictive bras
- Rest and stay hydrated to support milk flow
When It’s Worth Checking In With Your Doctor
Seek medical guidance if:
- The lump does not improve within a few days
- You develop fever, chills, or flu-like symptoms (possible mastitis)
- Pain or swelling worsens despite frequent feeding
- You notice pus, blood, or unusual discharge in milk
Key Takeaway
A clogged milk duct feels like a firm, tender lump that improves after feeding or pumping. Frequent milk removal, gentle massage, and warm compresses usually help, but medical care may be needed if symptoms persist or worsen.
