Mastitis: what to know

A tender, swollen, hot, or reddened area may develop in one breast. You may feel feverish, tired, achy, or shivery. Inflammation can follow milk stasis, pressure on the breast, feeding difficulties, or nipple damage; infection can also occur. A firm area does not by itself show whether infection is present.

Mastitis can make feeding painful, but stopping suddenly may worsen breast fullness. A feeding assessment can identify positioning, attachment, or pumping problems contributing to symptoms.

Continue breastfeeding or expressing only as needed for comfort, if you are able, and avoid forceful massage or trying to empty the breast repeatedly. Use comfortable support, rest, drink to thirst, and consider a cool pack for swelling. Arrange clinical advice if symptoms are significant, worsening, or not settling. A Lactation Consultation can help correct attachment and protect the nipple.

Seek prompt medical review for a high fever, rapidly spreading redness, severe illness, pus, a growing tender lump, or symptoms that do not improve. Emergency help is needed for confusion, breathing difficulty, or collapse. A breast abscess may need drainage, so persistent or localised swelling should be examined.

Ask whether the symptoms suggest inflammation, infection, or an abscess; whether you can continue feeding; what pain relief is suitable; and how soon you should be reviewed if the area remains swollen. Ask for help with attachment or pumping technique.
