Mastitis while producing breast milk

Inflammation can begin when milk production, breast swelling, and milk removal are out of balance. Pressure on the breast, nipple injury, an ineffective latch, pump problems, sudden changes in feeding, or oversupply may contribute. Bacteria may then be involved, but inflammation does not automatically mean there is a bacterial infection.

Mastitis often presents with breast pain, warmth, swelling, and an area of redness; fever, chills, body aches, and fatigue may accompany it. A distinct swelling that remains very tender or feels fluid-filled raises concern for an abscess, which requires direct assessment.

Continue breastfeeding in response to your baby's cues if you feel able, without trying to empty the breast. If feeding is too painful or the breast is uncomfortably full, gentle expression for comfort may help. Abruptly stopping can add to fullness, while repeated extra pumping can increase production and swelling.

Rest, drink according to thirst, apply a wrapped cold pack, and use pain relief that a clinician or pharmacist confirms is suitable for you. Do not deeply massage or squeeze the inflamed tissue. Medical review can determine whether antibiotics are appropriate and whether latch, positioning, pump fit, or oversupply needs attention.

Seek prompt advice if you have fever or chills, spreading redness, worsening pain, pus, marked weakness, or difficulty feeding or expressing because of symptoms. Also return for review when symptoms do not improve with the recommended care or worsen after treatment begins.

Emergency care is appropriate for confusion, fainting, breathing difficulty, or rapid deterioration. A growing, intensely painful, or soft-centred swelling needs urgent assessment for an abscess; drainage may be needed if a collection has formed.

Ask whether your symptoms suggest inflammatory or bacterial mastitis, whether examination or ultrasound is needed, and what changes should trigger another review. If antibiotics are prescribed, clarify how to take them, what side effects to watch for, and whether your baby's health changes any feeding advice.
