Breast engorgement and mastitis

Frequent, comfortable milk removal and attention to feeding technique can ease engorgement, whereas suspected mastitis may also need assessment and prescription treatment.

Engorgement often affects both breasts, making them feel firm, heavy, or tender when milk production and removal are out of balance. The nipple and areola may become taut, which can make attachment difficult. Mastitis usually produces a more localised painful, warm, or red area and may be accompanied by fever, chills, body aches, or marked tiredness.

Milk that is not moving comfortably can contribute to inflammation, but mastitis is not a sign of poor hygiene or personal failure. Symptoms may reflect inflammation alone or an infection that requires medicine; an examination helps distinguish what care is needed.

Continue breastfeeding or expressing at a comfortable, usual rhythm if you are able. Help the baby achieve a deep attachment, and express only enough to soften an overly full breast if feeding is difficult. Cool packs after a feed can reduce swelling; a supportive, non-restrictive bra can lessen discomfort. Rest, drink according to thirst, and avoid forceful massage or aggressive attempts to empty the breast, as these can worsen tissue irritation.

A lactation professional can watch a feed, check positioning and milk transfer, and help adjust pumping equipment. Ask a clinician or pharmacist which pain relief is suitable for you, particularly if you have allergies, other conditions, or take additional medicines.

Contact a clinician promptly if you have fever or flu-like symptoms, spreading redness, worsening focal pain, pus, or symptoms that are not improving with gentle milk removal and rest. Seek urgent care if you feel faint, confused, short of breath, severely unwell, or cannot keep fluids down. A persistent or enlarging tender swelling also needs assessment because a collection of fluid may require imaging and drainage.

Ask whether your symptoms fit engorgement, inflammatory mastitis, infection, or another breast problem; whether medicine is indicated; and how you should continue feeding or expressing. Also ask what improvement to expect, when to return, and whether a focal swelling needs ultrasound.
