Chills with breast engorgement: what to know

Engorgement often causes breasts to feel full, firm, heavy and tender when milk is accumulating or feeding patterns change. Chills are not a feature to dismiss when they occur with a hot, painful or reddened area, a wedge-shaped patch, fever or flu-like fatigue. Inflammation can occur before infection is confirmed, and symptoms can worsen if milk is not being removed comfortably. Other illnesses, including influenza, can also cause chills during the postpartum period, so breast findings and general symptoms should be considered together.

Continue breastfeeding or expressing as comfortably as advised, and avoid suddenly stopping. Use a comfortable supportive bra, rest, drink to thirst and apply brief cool packs for swelling. Check latch or pump fit if feeding is painful, and avoid forceful massage or excessive pumping, which can irritate tissue. Contact a lactation professional or clinician if the breast is not improving or feeding becomes difficult.

Contact a clinician promptly for chills with fever, a spreading red or hot area, worsening breast pain, pus-like nipple discharge, or feeling increasingly ill. Seek emergency care for confusion, fainting, severe weakness, breathing difficulty or rapidly worsening symptoms. A breast infection may need treatment, and delaying assessment can make feeding and recovery harder.

Ask whether the breast changes fit engorgement, blocked drainage, inflammation or infection; whether feeding should continue; how to manage pain; and which medicines are compatible with breastfeeding.
