Blocked milk duct after weaning: what to do

When feeds or pumping stop faster than the breasts adjust, milk can remain in a narrowed or inflamed area. You may notice local fullness, soreness, or a firmer patch. The breast may still leak or feel uneven while production winds down. A tender area alone does not establish an infection, but worsening inflammation can develop into mastitis.

Use a cool pack wrapped in cloth for short periods and wear a supportive bra that does not press into the sore area. If fullness is uncomfortable, hand-express only enough milk to soften the breast; repeatedly emptying it can signal the body to keep producing milk. Avoid deep massage, forceful squeezing, and trying to break up the area, because these can worsen swelling. A clinician or pharmacist can advise whether an anti-inflammatory pain medicine suits your health and other medicines.

Arrange prompt assessment if redness spreads, pain or swelling is increasing, or you develop fever, chills, flu-like feelings, pus, or feel markedly unwell. Seek care as well if the firm area does not ease, returns repeatedly, or a lump remains after breast fullness has settled. These changes may need an examination to distinguish inflammation, infection, an abscess, or another breast condition.

Ask whether your symptoms fit milk stasis or mastitis, how much milk to express for comfort, and which pain relief is appropriate for you. If a lump persists, ask whether you need breast imaging or follow-up and what change should bring you back sooner.
