Key points
- Call the same day for fever, chills, worsening pain, or feeling ill.
Breast inflammation deserves attention
Mastitis is inflammation of breast tissue. Sometimes it involves a bacterial infection. It can cause a tender, swollen area, warmth or redness, and flu-like symptoms.
Redness may be less visible on darker skin; pain, warmth, and swelling still matter.
What may contribute?
Oversupply, extra pumping, missed feeds, nipple injury, and pressure on the breast can contribute. Mastitis does not mean you have done something wrong.
What can help?
- Continue feeding according to your baby’s usual needs.
- If needed, express enough for comfort or to replace a feed.
- Use a cold pack wrapped in cloth.
- Rest and drink to thirst.
- Ask about appropriate pain relief.
Avoid deep massage, hard pressure, and repeated pumping to “empty” the breast. These can worsen inflammation. Bacterial mastitis may need antibiotics; an abscess—a pocket of pus—may need drainage.
When to contact your clinician
Call the same day for fever, chills, worsening pain, or feeling ill. Seek reassessment if treatment is not helping within 24–48 hours or a lump persists. Severe weakness, confusion, fainting, or breathing trouble needs emergency care.
Frequently asked questions
Is the milk usually safe?
Yes. Breastfeeding can generally continue with mastitis and commonly used treatments.
Should I suddenly stop breastfeeding?
Abrupt stopping can worsen discomfort. Ask for help making a gradual plan if you want to wean.
