Effects of mastitis

The breast may feel firm, tender or hot, with a wedge-shaped or localised red area. Fever, chills, body aches and exhaustion can occur. Inflammation may follow milk stasis, pressure on the breast, a missed feed or difficulty with attachment; infection can also be involved. Mastitis is not a reason to stop breastfeeding automatically. Milk removal and comfortable positioning are often part of recovery, but forceful massage or over-pumping can worsen swelling. A persistent lump may need examination to exclude an abscess or another breast problem.

Rest, drink to thirst and feed or express in a way that feels manageable. Check the baby’s latch and vary feeding positions; a lactation professional can help reduce pressure and protect the nipple. Cool packs between feeds may ease swelling, and simple pain relief may be suitable for you—check with a pharmacist if you are breastfeeding or have other conditions. Avoid tight clothing and deep massage. If symptoms are not settling or you feel increasingly ill, arrange a clinical review; antibiotics may be considered when bacterial infection is suspected.

Seek same-day advice for fever with a painful red breast, rapidly worsening symptoms, pus or blood from the nipple, or a lump that remains after inflammation improves. Get urgent help if you feel faint, confused, severely weak or unable to keep fluids down. A breast abscess may require drainage as well as medical treatment.

Could this be inflammation, infection or an abscess? Can I continue breastfeeding? What pain relief is compatible with my situation, and when should I expect improvement? Do I need a follow-up examination if the lump or redness remains?
