What Are Clogged Milk Ducts?
Clogged (or blocked) milk ducts happen when milk flow slows or stops in a section of the breast. It feels like:
- A small, tender lump in one area
- Redness or swelling
- Pain that worsens before or during feeding
- Possible decrease in milk flow on that side
Clogs usually resolve within 24–48 hours with correct management.
What Is Mastitis?
Mastitis is inflammation—often an infection—of breast tissue. It may start from a clogged duct that wasn't emptied or treated.
Symptoms of Mastitis
- Intense breast pain or burning
- Red streaks on the skin
- Fever over 38.5°C / 101.3°F
- Flu-like symptoms: chills, body aches
- Significant fatigue
Mastitis requires quick intervention and may need antibiotics.
Causes: Why Clogged Ducts & Mastitis Happen
- Infrequent feeding or pumping
- Poor latch or incomplete drainage
- Overproduction or sudden weaning
- Pressure on breast (tight bras, sleeping face-down)
- Stress or exhaustion, which can affect immune response
Home Remedies (Clogs & Early Mastitis)
These methods work best when caught early — ideally within 24–48 hours after symptoms begin.
Breastfeeding & Milk Removal
- Nurse or pump frequently, at least every 2 hours
- Start feeds on affected breast
- Massage the lump while baby feeds
- Change nursing positions (e.g., dangle feeding)
Use Heat & Massage
- Apply a warm compress before feeding
- Gently massage toward the nipple using circular motions
- Try soaking the breast in a warm Epsom salt bath
Cold After Feeding
- Use cold compresses after feeds to reduce inflammation
Stay Hydrated & Rested
- Drink fluids
- Get as much sleep as possible to support immune function
When You Need Medical Treatment
Don’t wait more than 24 hours if your symptoms worsen or a fever appears.
- Antibiotics may be prescribed for infected mastitis
- Prescribed anti-inflammatories (e.g., ibuprofen) help reduce swelling and pain
- Rarely, abscesses form and require clinical drainage
Always continue breastfeeding unless your provider advises against it.
Prevention Tips
- Feed on demand and avoid long gaps
- Ensure deep, efficient latch
- Avoid restrictive clothing
- Empty both breasts regularly
- Replace pump parts (valves/membranes) that could affect suction
Bonus Tip: Lecithin Supplements
Some lactation consultants recommend sunflower lecithin (1,200mg 3–4x/day) to prevent duct blockages by reducing milk “stickiness.” Ask your healthcare provider before starting.
Final Thoughts
Most clogged ducts clear up quickly. Mastitis, when caught early, is highly treatable. Don’t suffer in silence—you deserve support, care, and comfort during your breastfeeding journey.
