Mastitis causes and treatment

Mastitis can arise when milk is not moving comfortably, when the breast is compressed, or when irritated tissue becomes inflamed. A bacterial infection can also be present. Breast pain, a firm patch, warmth, and feeling unwell can occur together. Mastitis is different from a simple, painless fullness after a missed feed, although the conditions can overlap. A clinician may ask when symptoms began, whether you are breastfeeding, and whether there is nipple damage or a recurring area.

Continue breastfeeding or expressing in a way that feels manageable; abruptly stopping can worsen fullness. Use a comfortable position, avoid deep massage or forceful squeezing, and choose a supportive bra that does not press on the tender area. Rest, drink to thirst, and use a cool pack wrapped in cloth for swelling. A clinician can advise suitable pain relief and decide whether antibiotics are appropriate. A lactation consultation can help correct latch, positioning, or pump technique.

Arrange medical advice promptly if feverishness, chills, worsening redness, severe pain, or marked weakness develops. Seek urgent care for confusion, fainting, trouble breathing, or rapidly worsening illness. A persistent lump, a fluid-filled swelling, or symptoms that do not improve needs examination because an abscess or another breast problem may require different treatment.

Could this be inflammatory mastitis, an infection, or an abscess? Should I continue feeding or expressing from the affected side? Which pain-relief options suit me, and how should I check that the breast is improving? What should I change if the same area becomes inflamed again?
