Breast feeling lumpy and tender?
Read all about how blocked ducts happen and what you can do.

In your breast, milk flows through ducts to a number of tiny openings on the nipple. Sometimes these ducts can become blocked, milk builds up behind the blockage and you get a lump.
You may notice:
-
An area of your breast is lumpy or swollen.
-
It may look red and feel tender.
-
It may be painful especially when your let-down reflex happens.
Having a blocked duct is different from general engorgement.

How did I get a blocked duct?
Blocked ducts can happen at any time during breastfeeding.
-
Going longer between feeds.
-
If your baby sleeps for longer or sleeps overnight.
-
If feeds are rushed or baby doesn't drain your breast fully.
-
Some mums who make too much milk are more likely to get blocked ducts.
-
Due to injury, bruising or external pressure on the breast, eg tight bra, seatbelt, sleeping on stomach.
Relieving a blocked duct
Start treatment as soon as you feel a lump or sore spot. Taking the following steps may prevent the blocked duct from progressing to mastitis.
When feeding:
-
Feed as often as you can.
-
Feed from the affected breast first, when baby's sucking is stronger.
-
Check that your baby is attached well
-
Try different feeding positions to help empty the breast.
-
Gently massage the lump toward the nipple during feeds.
Before feeding:
-
Apply warmth to the affected breast before a feed to help your let-down reflex and encourage your milk to flow.
-
Try to relax to help your milk flow.
-
Make your breasts as comfortable as possible by taking off or loosening your bra during feeds.
After feeding:
-
Hand express after feeds if needed.
-
Cold packs after a feed may help relieve pain and inflammation.
See your doctor if you cannot clear the lump in a few days, or sooner if you develop a fever or feel unwell. Mastitis can result from a blocked duct that doesn’t clear.
How can I prevent it from happening again?
-
Feed your baby often.
-
Wear comfortable clothing so there is no pressure on your breasts.
-
Rest when you can, eat well and drink enough water.
