Engorgement Relief When Milk Won’t Flow

When a breast becomes overfull it is said to be “engorged”. Engorgement is very common in the early weeks after birth when there will be extra blood and tissue fluid within the breast as well as the milk supply coming in. A breast may also become engorged with milk at any time, e.g. if a baby sleeps longer than usual and misses feeds or if a baby isn’t draining the breasts properly due to a poor latch (the way baby attaches to the breast) or a blocked milk duct. Sometimes tight clothing pressing on the breast can cause engorgement.

Relieving engorged breasts

At the first sign of discomfort, it is important to express some of the milk from the breasts until they feel comfortable again. This can be done by hand expressing, using a breast pump, or ideally by your baby breastfeeding well to drain the breasts. By expressing to comfort, or feeding her baby frequently, a mother will avoid having very sore and tender breasts, and reduce the risk of painful mastitis symptoms or developing an abscess. Ideas for engorgement relief  are described further in Engorged Breasts and include a combination of breast drainage, massage, cold therapy, and suitable anti-inflammatory medication. But what if milk won’t flow and no amount of pumping seems to yield any milk to relieve the engorgement? This article offers ideas for relieving breast engorgement when milk won’t flow.

Milk not letting down

When a baby starts to breastfeed, milk is released from the breast in a neurohormonal reflex (involves nerves and hormones) known as the milk ejection reflex or “let-down”. Sometimes engorgement can be so severe that a mother can’t seem to get her milk to let-down at all, her breasts will feel hard, lumpy and very painful. The mother may describe them as being “blocked” or that “the milk is stuck” and she just can’t express any milk. Her baby, who would normally be the ideal trigger for a let-down, may also be refusing to latch, or be unable to latch because the nipple or breast may have changed shape. In these situations even a very good pump may not always help—because it may make the congestion or swelling (oedema) worse by pulling more tissue fluid and blood into the engorged area.

Traffic jam?

When an area of the breast is severely engorged, it can prevent everything behind it from flowing forward, much like a traffic jam might prevent traffic moving throughout a town centre. Another analogy compares severe breast engorgement to stepping on a hose full of water (obstructing the flow).

When milk won’t flow, milk will go

Severe engorgement of this type is a high risk factor for mastitis (painful breast inflammation) and for the mother’s milk supply to be reduced. The increasing local pressure of milk within the breast is thought to slow milk production through chemical messengers (feedback inhibitors) and mechanical means1. In view of the risk to her milk supply, not to mention the discomfort, how can a mother get engorgement relief if she can’t get any milk out?

Tips for engorgement relief when milk won’t flow

While trying the tips below, it is a good idea to work with an IBCLC lactation consultant and your health professionals and to check for symptoms of mastitis.

Breast massage and hand expression

A gentle breast massage can really help to get milk flowing and prepare the breasts to release milk. Breast massage should not be painful and finger tip pressure need only be as light as you would use when applying a cream or ointment to your skin. The massage video below from Maya Bolman of Breastfeeding Medicine of Northeast Ohio shows gentle rolling, kneading and tapping techniques to get the breasts ready for expression and shows a gentle breast massage technique to alternate with hand expressing. Alternating massage with hand expressing can help to gently clear the “traffic jam” behind the nipple. For further tips and videos to help with hand expressing see Hand Expressing Breast Milk.

Sit up or lie down

A mother can sit up for the massage as in the video or a mother may find that lying on her back and massaging her breast with circular movements (see video from 2:51) prior to hand expressing can be more effective.

Using a comb

Anecdotally some mothers have found using a wide tooth comb to gently stroke an engorged breast can help circulation and drainage. Marsha Walker likens this to the Asian practice of gua-sha therapy 2.

Lymphatic breast drainage

Sometimes breast engorgement is not caused by breast milk and increased blood circulation alone. Other fluids can add to the pressure in the breast causing oedema or swelling particularly in the first week or two after birth. A mother who has been on an intravenous (IV) drip is more likely to experience swelling and engorgement caused by this type of water retention in her breasts during the first ten days after birth3. If this is the case, the breast massaging technique featured in the video above will help move the extra fluid out of the breast via the lymphatic system (a drainage system for tissue fluid in the body). A mother may like to semi recline or lie flat on her back for the massage so that gravity can help to drain the fluids via the lymphatic system alongside gentle massage towards the armpits.

Reverse pressure softening

A version of breast massage, known as reverse pressure softening can help bring out a nipple flattened by engorgement by redistributing the fluid behind the nipple. Using your fingers, the fluid in the compacted area can be gently moved away from the nipple sending it temporarily deeper into the breast. This can help a baby who is struggling to latch to a full breast and can also begin to release the “traffic jam” behind the nipple. See Engorgement Help: Reverse Pressure Softening by Jean Cotterman, for the technique. Using a combination of reverse pressure softening and general breast massage may be most helpful.

Breast shells

Commercial breast shells can provide gentle pressure to a swollen areola instead of fingers to achieve reverse pressure softening and expose the nipple 4.

Cold is your friend

Cooling the breasts whether by using crushed ice or frozen vegetables in a damp cloth against the engorged areas or by placing a chilled cabbage leaf in the bra, causes blood vessels to constrict (get smaller). This reduces blood flow to the area, and reduces swelling which helps with lymphatic drainage of tissue fluid in the breast. Applying cold therapy has not been shown to cause any problems for let-down or milk transfer and it helps with pain5.

Cabbage Leaves

Breastfeeding specialists do not always agree whether cabbage is an evidenced based or useful cure for engorgement. If nothing else, a chilled cabbage leaf in the bra will be a “cold friend” to your breasts. A 2017 study concluded cabbage leaves were better than cold gel packs at reducing engorgement6. If you decide to try them, Dr Jack Newman, a Canadian paediatrician, writes:

Take a green cabbage, remove the outer leaves and discard them. Then take a few of the inner leaves and place them on the breast after feeding, inside your bra. The curved shape helps them fit nicely. Some suggest crushing the leaves with a rolling pin to help them fit the shape of the breast. Actually, there is no agreed upon protocol for using cabbage leaves. Some lactation specialists suggest using them after each feeding and keeping them on for 20 minutes or so. Some suggest keeping them on until they wilt, or until you need to feed your baby. Some suggest using them only three or four times a day. Experiment and see what works for you.

Warmth in moderation only

Warmth applied to the breasts prior to hand expressing or pumping can help trigger a let-down. Some mothers have found success suspending their breasts in warm water by leaning over a sink or bowl and letting gravity, warmth, and gentle massage help. Letting warm water run down your back in a shower may also help get milk flowing. However, be very wary of popular advice to apply excess heat to a swollen breast; this will cause blood vessels to dilate bringing extra blood rushing to the area which is likely to make the engorgement even worse. Marsha Walker IBCLC explains:

Heat application in the form of hot compresses, hot showers, or hot soaks is poorly researched and has usually been more of a comfort measure to activate the milk ejection reflex, rather than a treatment for oedema. Some mothers complain that heat exacerbates the engorgement, causes throbbing and an increased feeling of fullness.


Engorgement causes inflammation so suitable anti-inflammatory medication can help with pain and symptoms. Several pain killers (Breastfeeding Network) are compatible with breastfeeding. The Academy of Breastfeeding Medicine Protocol #20 Engorgement reports on the success of an anti-inflammatory enzyme drug serrapeptase 7 and other enzyme therapy.

Note: some medications could be a cause of difficulty with milk release as could excesses of caffeine, smoking, or alcohol.

Try a different pump or check pumping equipment

If you want to try a breast pump but cannot get milk flowing with your regular pump, consider whether your pump is working properly, whether the flanges are a good fit or whether you could afford a better model. See How to Increase Milk Supply When Pumping for more information on choosing a pump or where to hire a good hospital grade pump. Bear in mind that pumping a severely engorged breast on too high a setting, or pumping in the early days after birth—may be counterproductive for reasons mentioned above, at least until the milk is flowing again.

More ideas for engorgement relief

Find a breastfeeding specialist

Working with a IBCLC lactation consultant can be invaluable for support to find the quickest route to thorough breast drainage and to avoid future engorgement episodes.

“Juice Jar” breast pump

Kelly Bonyata describes how to use a one litre glass jar or bottle (with a 5cm or larger opening) to create a vacuum around the breast to both stimulate a let-down and help draw out a flattened nipple. Her method:

  • Fill the glass container with very hot water to heat the glass, be careful not to burn yourself (wrap it in a towel).
  • Empty out the water and cool the mouth of the bottle with a cold cloth to skin temperature.
  • Place the breast in the cooled mouth of the jar, check there is a good air tight seal.
  • As the air inside the jar slowly cools, a vacuum will be created that releases milk from the breast.

Called the “Juice Jar” breast pump it is described more fully in Engorgement by Kelly Bonyata. A commercial device that works on a similar principle using a vacuum effect is the Haakaa Silicon Breast Pump, for more information about this pump see This Year’s Big Thing… by Shel Banks IBCLC.

Oxytocin nasal spray

If you are still unable to get milk to let-down after trying the techniques above, synthetic oxytocin as a nasal spray is available on prescription in some countries, and may be helpful 8. Breastfeeding authors West and Marasco have this to say about dosage:

The usual dosage is one spray (three drops) in each nostril two to three minutes before breastfeeding or pumping. The use of synthetic oxytocin to aid milk ejection is usually temporary and rarely required for longer than a week.


In Making More Milk the authors describe herbs that can help facilitate milk ejection (let-down). They point out that they may work by increasing milk supply (galactagogues) rather than helping the actual let-down, therefore they could be problematic for the mother who is struggling to find engorgement relief while milk won’t flow. Use any herbs with caution and check with your health professional.

[Galactagogue herbs with a reputation for helping with let-down] include anise, black cohosh, blackseed, chasteberry, dill, fennel, hops, and red raspberry leaf.

Fenugreek seed poultice

Kelly Bonyata describes a fenugreek poultice traditionally thought to help with release of milk as follows:

Steep several ounces of fenugreek seeds in a cup or so of water. Let seeds cool, then mash them. Place on a clean cloth, warm, and use as a poultice or plaster on engorged or mastitic breasts to help with let-down and sore spots.

Medical causes for impaired let-down

There can be medical causes for difficulty with the milk ejection reflex. These include thyroid conditions and any damage to important nerves such as might happen during breast or brain surgery.

Thyroid conditions

Problems with milk release (let-down) appear to be a bigger issue than low milk supply where mothers have hyperthyroidism or hypothyroidism. If the milk can’t be removed from the breast then the local control mechanisms in the breast will begin to reduce milk production. Medication to address the thyroid imbalance and assistance with milk release such as synthetic oxytocin spray, breast massage prior to feeding and breast compression may help propel milk from breast to baby9.

Breast surgery

If the fourth intercostal nerve (located by the nipple) has been damaged, for example by breast surgery (including breast implants or breast reduction), this can interfere with release of oxytocin and prolactin from the brain and affect the let-down reflex (West and Marasco, 2009).

Severe stress

Further possible causes for difficulty with let-down (with or without severe engorgement) include pain, grief and loss, previous sexual abuse, severe stress and birth trauma (Making More Milk Chapter 10).

Caffeine, smoking, alcohol, medications

Caffeine, smoking, alcohol and some medications could be potential causes for difficulty with the let-down reflex.

Body work

If neurological function of key nerves involved in milk release are impaired, or spinal vertebrae misaligned, body work or manual therapy is reported to have helped some mothers with milk production and let-down 10.


Sometimes breast engorgement can be so severe that the breast seems to be “blocked’ and milk won’t flow. There are several techniques that can be useful to get breast milk flowing and release the pressure of breast milk in the breasts. It is important to relieve the engorgement to prevent mastitis and to avoid damage to the mother’s milk supply.
