Mastitis symptoms: When to Contact a Health Professional

Mastitis means inflammation in the breast and can make you feel unwell quickly. It often affects one area, with pain, heat, swelling or a firm patch. Infection can occur, but not every inflamed breast needs antibiotics. A clinician can assess the symptoms and decide what treatment and follow up are appropriate.

Notice more than skin colour

You may develop fever, chills, aches or unusual tiredness alongside breast pain. Redness can be harder to see on darker skin, so warmth, tenderness and swelling matter too. Tell the clinician when symptoms began and whether they are spreading or getting worse.

Seek prompt medical advice if you feel unwell or symptoms are worsening. If mild symptoms are not improving after 12 to 24 hours of gentle care, contact your clinician. Confusion, difficulty breathing or feeling seriously unwell needs emergency help; do not wait for that review interval.

Keep care gentle while arranging help

Continue usual responsive breastfeeding if you can tolerate it, rather than trying to empty the breast repeatedly. If direct feeding is too painful or ineffective, ask for an expression and milk feeding plan. The painful breastfeeding guide explains what to include in an assessment.

A cold cloth or wrapped cold pack may ease discomfort. Use a supportive bra that does not squeeze the breast, and ask a pharmacist or clinician about suitable pain relief. Your medical conditions and other medicines can affect what is appropriate.

Avoid forceful attempts to clear the breast

Do not dig into a lump, use deep massage or add repeated pumping sessions to force milk out. Extra milk removal can increase production, and strong pressure can worsen tissue inflammation. Avoid prolonged heat and unadvised oils or soaks.

If fullness is the main issue, the engorgement guide discusses related comfort measures. However, fever or increasing illness should not be dismissed as ordinary fullness. Abruptly stopping breastfeeding can also worsen discomfort; get support if you want to reduce feeding gradually.

Make sure treatment is reviewed

If antibiotics are prescribed, follow the instructions and contact the clinician if symptoms worsen or do not begin improving within 48 hours. You can usually continue breastfeeding during treatment. Ask about your particular medicine if you are unsure rather than discarding milk automatically.

A persistent or enlarging painful lump, especially with warmth or swelling, needs urgent assessment for a possible abscess or another cause. An abscess may require ultrasound and drainage as well as medicine. Do not squeeze or puncture it yourself. Recurrent symptoms also deserve review so the next plan addresses the underlying problem rather than repeating treatment indefinitely.
