Why do I get clogged milk ducts?
Last updated September 3, 2026.
A clogged duct is a tender lump from milk backing up - clear it with frequent feeding, warmth before feeds, gentle massage. Fever, chills, and a red hot breast area mean mastitis: call your provider promptly.
What to do
- Keep milk moving - frequent feeds starting on the sore side, per NHS guidance.
- Warmth before, cold after - and gentle massage toward the nipple during feeds.
- Chin toward the lump - positioning drains the clogged area.
- Fever or red hot breast: call promptly - mastitis usually needs antibiotics.
