Mastitis and Breastfeeding

Breastfeeding mastitis may follow a difficult latch, pressure on the breast, a sudden change in feeding, or milk that is not moving comfortably. Inflammation can cause a hot, painful, swollen, or red area, a firm patch, and sometimes feverishness or body aches. Painful breastfeeding itself can lead to shorter feeds, which may increase fullness and discomfort. Bacteria may contribute, particularly when nipple skin is damaged, but symptoms need assessment rather than assumptions about the cause.

Continue breastfeeding or expressing milk if you can do so comfortably; stopping abruptly may worsen fullness. Offer feeds responsively, check your baby’s attachment, and use positions that avoid pressure on the sore area. Rest, drink to thirst, wear non-tight clothing, and use a cool pack wrapped in cloth. Avoid forceful massage, vigorous pumping, and attempts to completely empty the breasts. A lactation consultant can help with latch, nipple pain, feeding frequency, and a plan that protects both recovery and milk supply. Check any medicine with a healthcare professional.

Get prompt medical advice for fever, chills, rapidly spreading redness, severe pain, pus, or feeling faint or very unwell. Contact a clinician if symptoms are worsening, do not start improving, or return after they settle. A persistent lump or soft swelling may be an abscess and needs assessment. Do not stop breastfeeding solely because you fear the milk is harmful; ask for individualized advice about your symptoms and treatment.

Ask whether you can continue feeding, whether your baby’s latch needs review, which treatment is compatible with breastfeeding, and when a persistent lump should be checked.
