Body aches and mastitis: what to know

Mastitis is inflammation of breast tissue and is common during breastfeeding, although it can occur in other circumstances. A blocked milk duct, bacteria entering through a damaged nipple, or another breast problem may be involved. Body aches may appear as part of the body's inflammatory response. Chills, marked tiredness, fever, or a rapidly enlarging red area make infection more concerning, while aches without breast changes may have a separate cause such as influenza or another viral illness. The symptom pattern does not by itself establish mastitis.

Rest, drink fluids, and continue breastfeeding or expressing milk if you are able and it is comfortable; sudden stopping can worsen breast fullness. Feed or express regularly, check that the baby's latch is comfortable, and use a cool pack wrapped in cloth for short periods. Avoid forceful massage, tight clothing, and prolonged heat. A clinician can assess whether antibiotics or another treatment is appropriate, particularly if symptoms are worsening or do not start improving.

Arrange prompt medical assessment for a painful hot or red breast, a firm area that persists, pus or blood in nipple discharge, or symptoms that are getting worse. Seek urgent help for confusion, fainting, trouble breathing, severe weakness, or inability to keep fluids down. If you are breastfeeding and feel significantly unwell, contact a clinician the same day.

Ask whether the breast findings fit mastitis, whether a culture or imaging is needed, and which pain medicines are suitable while breastfeeding. Mention when the aches began, any fever or chills, nipple damage, recent feeding changes, and previous episodes.
