Clogged ducts and mastitis

The breast may feel sore, warm, firm, or swollen. Mastitis can present with a red or darker patch, increasing pain, fever, chills, and a flu-like feeling. A hard area is not necessarily a plug that needs to be forced out.

Milk-duct narrowing and swelling can develop when milk production exceeds removal, feeding patterns change, or pressure is placed on the breast. Inflammation may remain local or become more extensive; bacterial infection can occur in some cases.

Forceful massage and repeated extra pumping can aggravate swelling or drive further milk production. Painful breastfeeding may also reflect shallow attachment, nipple damage, pump settings, or positioning, all of which can keep the breast irritated.

Continue breastfeeding or expressing according to your baby's needs if you are able; milk from the affected breast is generally suitable for the baby. Avoid trying to empty the breast repeatedly. Use a cool pack wrapped in cloth after feeds, rest, drink to thirst, and choose a supportive bra that does not press on the sore area.

Keep touch light rather than digging into the breast. Check that the pump flange and suction are comfortable. A lactation consultation can help adjust attachment, feeding position, and pumping while protecting milk supply. Ask a pharmacist or clinician which pain relief is suitable for you, especially if you have another medical condition or take other medicines.

Arrange same-day medical advice if you feel systemically unwell, have fever or chills, redness is spreading, pain is worsening, or symptoms are not improving with gentle measures. A clinician can assess whether antibiotics are needed and check for a collection of pus called an abscess.

Seek urgent help for confusion, fainting, difficulty breathing, severe weakness, or rapidly worsening illness. Prompt reassessment is also needed if symptoms continue despite prescribed treatment or a soft, fluid-filled swelling develops.

Ask whether your symptoms suggest inflammation alone, bacterial mastitis, or an abscess; whether an examination or ultrasound is needed; and how to keep feeding comfortably. If medicine is prescribed, confirm the dose, course, compatibility with breastfeeding, expected improvement, and reasons to return.
