Today, we’re talking about blocked ducts — when inflammation causes milk ducts to narrow.
This can be caused by:
• sudden changes in feeding patterns
• latch issues
• pressure on the breasts from bras, clothing, or fingers during feeding
• knocks and bumps
You can continue to feed or express as normal — this will help ease discomfort. Avoid trying to empty the breast, as this can lead to oversupply.
If you choose to massage, it’s important to be gentle. Any pressure should be no firmer than stroking a cat 🐱
A warm compress on the ni**le may help with let-down - not too hot, or often, as this could increase the swelling. A cool compress on the inflamed area may help ease symptoms between feeds.
If you experience blocked ducts frequently, speaking with one of our peer supporters may help. They can look at feeding positions, latch, and feeding patterns if needed.

It’s also important to watch for early signs of mastitis. Symptoms may include breasts that are painful and/or hot to the touch, and changes in skin colour (reddened or darker areas, depending on skin tone).
If you start to feel ill, dizzy, confused, or develop nausea, vomiting, diarrhoea, or slurred speech alongside mastitis symptoms, please seek urgent medical attention.

[ID: What are blocked ducts? Blocked ducts. (Inflamed ducts/ductal narrowing). Researchers now think that ducts don't become blocked or plugged with thickened milk. Milk ducts can narrow due to inflammation, which may cause milk to 'back up' behind swollen lumps. Attempting to unblock a 'plug' by squeezing or aggressively massaging your breast isn't likely to be effective and may damage the tissue.]
