What should you know about Pseudomonas mastitis?

Mastitis can cause a painful, warm, swollen or reddened area of the breast, sometimes with fever or a flu-like feeling. Pseudomonas is one possible bacterial cause, but symptoms alone cannot identify the organism. Inflammation can also occur without a bacterial infection. Recent antibiotics, breast damage, milk stasis or healthcare exposure may affect the clinician’s assessment, so a clear history matters.

Seek clinical advice when breast inflammation is significant, worsening or not settling. Continue breastfeeding or expressing if it is comfortable and advised; sudden over-pumping or forceful massage can worsen swelling. Use gentle milk removal, supportive clothing, fluids and suitable pain relief if safe for you. A clinician may take a milk sample or choose an antibiotic based on the suspected organism and your feeding situation. A lactation consultation can help correct latch and milk-removal problems.

Get urgent help for a rapidly enlarging red area, severe pain, high fever, confusion, faintness, pus, or a soft swelling that may indicate an abscess. Arrange reassessment if symptoms do not improve, return after treatment, or you feel increasingly unwell. Persistent breast changes outside a clear episode of mastitis also need examination rather than repeated self-treatment.

Could this be bacterial infection, inflammation without infection or an abscess? Is a milk culture needed? Which treatment is compatible with breastfeeding? Would a lactation consultation help with latch, pumping or milk removal?
