Mastitis and Bacterial Infection

Mastitis is inflammation of the breast. During breastfeeding, swelling and milk-flow problems can irritate tissue; bacteria can then enter through damaged skin around the nipple or multiply in inflamed tissue. A painful, warm, red or firm area may occur with feverishness, chills, fatigue, or body aches. Symptoms alone cannot confirm the cause. A clinician may examine the breast and look for a collection of pus, called an abscess, which may need imaging or drainage.

Keep milk moving in a comfortable way by feeding or expressing as tolerated, and avoid abruptly stopping if that makes the breast fuller. Check the baby’s attachment and vary positions so pressure is not concentrated in one spot. Rest, drink fluids, use a cool pack for swelling, and avoid deep massage or squeezing the breast. A clinician may prescribe an antibiotic when bacterial infection is suspected. Take it exactly as directed and ask what to do if symptoms are not improving. Lactation support can address the feeding problem that helped trigger inflammation.

Get prompt medical advice if you have fever, chills, rapidly expanding redness, severe pain, pus, or feel unusually weak or ill. Seek reassessment when symptoms are worsening, fail to improve, or return after treatment. A persistent lump or soft, fluid-like swelling requires examination because an abscess may need a procedure. Do not delay care while trying different supplements or topical remedies.

Ask whether infection is suspected, how long improvement should take, whether testing or an ultrasound is needed, and which pain-relief options are suitable while breastfeeding.
