How to tell the difference, and what to do about it
Breastfeeding can come with bumps in the road—literally. Here’s how to tell whether you’re dealing with a plugged ductor mastitis, and what you can do to feel better fast.
What Causes It?
These are common triggers for both conditions:
• Skipped or delayed feedings
• Poor latch or ineffective milk removal
• Oversupply or hurried feedings
• Pressure on the breast (tight bra, bag strap, sleeping position)
• Stress, fatigue, or weakened immunity
• Nipple damage (especially for mastitis risk)
What Can I Do at Home?
Whether it’s a plug or mastitis, early treatment is key.
General Self-Care
• Rest (ideally with baby in bed if possible)
• Hydrate well – water, broth, herbal teas
• Eat nutrient-rich meals
• Ask for help at home!
• Epsom salt silicone pump soak (details below)
Before Feeding
• Apply heat (warm compress, soak, or shower)
• Gently massage toward the nipple to encourage drainage
• Loosen any tight clothing or bras
During Feeding
• Feed frequently, starting on the affected side
• Try dangle feeding (leaning over baby) for gravity assist
• Use gentle breast compressions
• Make sure baby is well-latched and nursing effectively
After Feeding
• Use cold compresses to reduce swelling and pain
• Continue massaging the area gently
• Pump or hand express if baby doesn’t fully drain the breast
Medication Support
• Pain relief: Use ibuprofen (anti-inflammatory) or acetaminophen
• Antibiotics? Plugged duct: Not needed / Mastitis: May not be needed right away. But if symptoms last >24 hours, worsen, or you’re very ill, antibiotics are often appropriate.
• Consult your healthcare provider if in doubt.
Antibiotics are especially important if you:
• Have red streaks on the breast
• See pus or blood in milk
• Are acutely ill with chills or fever
• Recently gave birth or were in the hospital
• Have broken nipple skin with signs of infection
What Might Milk Look Like?
Plugged Duct:
• Milk may appear “stringy,” thick, or fatty
• Supply may temporarily dip in the affected breast
Mastitis:
• Milk may be salty, clumpy, stringy, or even contain mucus or blood
• This milk is safe for baby, though some may refuse the taste
When to Call for Help
Reach out to your lactation consultant or care provider if:
• Symptoms don’t improve within 24–48 hours
• You have two or more episodes in the same spot
• You feel worse after starting antibiotics
• Baby refuses the breast or shows signs of poor intake
• You suspect a milk blister or thrush
