How common is painful breastfeeding in mastitis?

Mastitis is inflammation in breast tissue during the breastfeeding period. The affected breast may feel sore, heavy, firm, hot, or painful when milk is removed. Nipple pain can also come from shallow attachment, friction, skin damage, or a blocked milk duct, so pain by itself does not identify the cause.

When mastitis is present, discomfort may be concentrated in one area or spread through the breast. Some people also feel tired, achy, feverish, or generally unwell. Feeding may hurt at the start, throughout a feed, or when the breast is touched.

Continue breastfeeding or expressing milk in a comfortable, usual pattern if you can; abrupt stopping can make breast fullness worse. Offer the tender breast when your baby is ready, but avoid forceful massage, repeated extra pumping, or trying to empty the breast completely.

Rest, drink to thirst, and use a cool pack wrapped in cloth for short periods to ease swelling. Check your baby's attachment and position, because reducing nipple friction can make feeds more tolerable. A lactation professional can watch a feed and help adjust the latch.

Contact a clinician promptly if you feel feverish or very unwell, the redness or swelling is spreading, pain is worsening, or symptoms are not starting to improve with supportive care. Seek urgent help for severe weakness, confusion, breathing difficulty, or signs of a serious allergic reaction.

A clinician can examine the breast and check whether an infection, collection of pus, nipple injury, or another problem needs treatment. Do not delay assessment because breastfeeding is painful, especially when you also have a persistent hard area or worsening illness.

Ask: Could the pain be related to mastitis, latch, nipple injury, or another breast problem? Should I continue feeding from the tender side? What changes would mean I need a same-day examination?
