What should you know about start of mastitis symptoms?

Mastitis is inflammation of breast tissue. It can occur during breastfeeding when milk flow is uncomfortable or restricted, and infection may or may not be involved. The affected area may feel firm, hot or painful, with skin redness on one side. Some people develop chills, fatigue or a raised temperature. Painful breastfeeding can contribute to feeding difficulty, but nipple pain and breast inflammation are not interchangeable diagnoses.

Prioritise rest, fluids and comfortable milk removal. Feed or express according to your baby’s needs and comfort, checking attachment and position rather than trying to empty the breast forcefully. Use a cool pack wrapped in cloth for discomfort and avoid tight clothing or deep massage. If symptoms are getting worse or you feel unwell, contact a clinician the same day for tailored advice.

Arrange prompt medical care for feverishness, chills, spreading redness, worsening swelling, pus, or a painful lump that persists. Seek urgent help if you feel faint, confused, severely weak or short of breath. A clinician can distinguish inflammation from infection and check for an abscess when symptoms do not settle.

Ask how to manage feeding or expressing, whether medication is needed, and which changes should prompt review. If breastfeeding is painful, ask for a lactation consultation to check attachment and protect your nipples while symptoms improve.
