Postpartum Problems of the Breast

Postpartum breast problems by symptom

Engorgement

When milk "comes in", usually 2 to 5 days after birth, extra blood flow, fluid and milk make the breasts swollen, firm and sore. It may cause a low-grade temperature. Engorgement can flatten the nipple, making latching harder.

What helps:

• Feed on demand, 8 to 12 times in 24 hours.
• Gently hand express a little milk to soften the areola before latching.
• Use cold packs between feeds to reduce swelling.
• Try gentle lymphatic drainage: very light strokes from the nipple toward the armpit.
• Take ibuprofen or acetaminophen (paracetamol) as directed on the label. Both are compatible with breastfeeding.

For people not breastfeeding, engorgement settles within about 7 to 10 days. A supportive bra, cold packs, pain relief and avoiding nipple stimulation help. Expressing only enough to relieve discomfort avoids stimulating more milk.

Sore and damaged nipples

Some tenderness in the first week is common. Pain that lasts through the whole feed, nipples that look flattened or creased like a new lipstick after feeds, cracks or bleeding usually mean the latch needs adjusting. Tongue-tie in the baby can contribute. An international board-certified lactation consultant (IBCLC) can help. Air-drying, a little expressed milk or purified lanolin can ease soreness.

Nipple vasospasm causes nipples to turn white, then blue or red after feeds, with throbbing or burning pain, often triggered by cold. Warmth after feeds helps.

Blocked ducts and the mastitis spectrum

Current guidance from the Academy of Breastfeeding Medicine describes a spectrum rather than separate conditions. Narrowing of milk ducts from swelling, often linked to oversupply, causes a firm, tender area. If inflammation increases, it becomes inflammatory mastitis. Bacteria can then cause bacterial mastitis, which may lead to an abscess.

Updated advice for a tender lump or early mastitis:

• Keep feeding normally from the affected side. Milk is safe for the baby.
• Do not massage deep and hard, or pump extra to "empty" the breast. Overpumping increases supply and inflammation.
• Use ice for 10 to 20 minutes and ibuprofen to reduce swelling.
• Use a well-fitting bra and avoid pressure from tight straps or sleeping on your front.
• Rest, fluids and help with other tasks.

See a clinician if: you have fever, flu-like aches, or it is not improving within 24 to 48 hours. Antibiotics compatible with breastfeeding are used for bacterial mastitis. See lactational mastitis.

Breast abscess

An abscess is a collection of pus, usually after mastitis. It feels like a tender, sometimes soft lump with redness. Ultrasound confirms it, and it is treated with needle drainage, sometimes repeated, and antibiotics. Most people can continue to breastfeed, even from the affected side.

Thrush

Candida yeast can infect the nipples, causing burning nipple pain and shooting breast pain, especially after recent antibiotics or if the baby has white patches in the mouth or a diaper rash. Both parent and baby are treated with antifungals. Thrush of the deep breast ducts is debated, and bacterial causes are now thought to explain many cases once blamed on yeast. See thrush.

Lumps that need checking

Most postpartum lumps are related to milk. A lump that does not shrink within 1 to 2 weeks, is hard, fixed or irregular, or comes with skin dimpling, nipple inversion that is new, or persistent redness and thickening without fever should be imaged with ultrasound. Breast cancer during or soon after pregnancy is uncommon but can be missed because changes are blamed on breastfeeding. Ultrasound and even mammograms are safe while breastfeeding.

Getting help

• Your obstetrician, midwife or primary care doctor for fever, infection or lumps
• A lactation consultant for latch, supply and nipple problems
• Your baby's pediatrician for tongue-tie, feeding and weight gain

Persistent breast pain makes breastfeeding much harder and is linked to postpartum depression, so ask for help early.

Frequently asked questions

What are common breast problems after birth?

The most common are engorgement when milk comes in, sore or cracked nipples, blocked or inflamed ducts and mastitis. Less common are breast abscesses, milk-filled cysts called galactoceles, and thrush. Most improve quickly with good feeding support and timely treatment.

How do I know if I have mastitis or a clogged duct?

A clogged or narrowed duct causes a tender lump without fever and you feel well. Mastitis usually causes a red, hot, painful area, often wedge-shaped, with fever, chills and flu-like aches. If you have fever or symptoms are not improving in 24 to 48 hours, see a clinician.

Should I keep breastfeeding with mastitis?

Yes. Continuing to feed normally from both breasts is safe for your baby and helps recovery. Avoid overpumping or aggressive massage, which can worsen inflammation. Antibiotics prescribed for mastitis are chosen to be compatible with breastfeeding.

Why is there a hard lump in my breast while breastfeeding?

Most lumps are inflamed milk ducts, which soften after feeds within a few days, or a milk cyst. A lump with fever may be mastitis or an abscess. A lump that persists beyond 1 to 2 weeks or feels hard and fixed should be checked with an ultrasound.

How long does engorgement last?

Engorgement usually peaks 3 to 5 days after birth and settles within 24 to 48 hours with frequent feeding. In people who are not breastfeeding, it can take 7 to 10 days to resolve. Cold packs, a supportive bra and pain relief help in the meantime.
