Can mastitis make you sick?

Mastitis is inflammation of the breast. Alongside a painful, warm, swollen, or red area, some people develop a raised temperature, chills, body aches, headache, tiredness, or nausea. These symptoms reflect the body’s inflammatory response and may also occur when bacteria are involved. A breast lump or sore area can be caused by inflammation and does not by itself identify the cause.

The intensity of symptoms can change over a short period. Breastfeeding, a blocked-feeling area, nipple injury, pressure from clothing, or a recent change in feeding pattern may be relevant when a clinician assesses you.

Rest when possible, drink to thirst, and continue comfortable breastfeeding or expressing rather than abruptly stopping. Avoid deep massage, tight clothing, and repeated pumping beyond your baby’s needs. Cool compresses can reduce discomfort between feeds. Note your temperature, the spread of redness, and whether you can eat, drink, and care for yourself. Breast pain and painful breastfeeding deserve attention because correcting latch or positioning can reduce strain. A lactation consultation may help with feeding technique.

Contact a healthcare professional promptly if feverishness or chills are strong, you feel increasingly unwell, redness is spreading, pain is escalating, or a firm area becomes larger or more fluctuant. Arrange review if symptoms fail to improve with supportive care. Seek urgent help for confusion, fainting, breathing difficulty, inability to drink, or very little urine.

Ask what may be driving your symptoms, whether you need an examination or treatment, how to monitor a breast lump, and which medicines are compatible with breastfeeding. Tell them about fever, chills, nipple injury, allergies, and any recent feeding changes.
