Mastitis NZ: Signs, Relief and When to Call Your Midwife

If your breast suddenly feels hot, hard and tender, and you've come over all shivery and achy like you're getting the flu — you might be dealing with mastitis. It's one of the most common breastfeeding hiccups for new mums in Aotearoa, and while it can feel frightening when it comes on fast, the good news is that most cases settle with gentle care at home and the right support from your midwife. Here's what to look for, what helps, and when it's time to pick up the phone.

What is mastitis, really?

Mastitis is inflammation of the breast tissue, sometimes (but not always) with an infection on top. It often begins as an area of the breast that feels swollen, firm and sore — a sign that part of the breast is overfull or inflamed. When that inflammation builds, the area can become red, hot to the touch and painful, and you may start to feel genuinely unwell.

It's most common in the early weeks of breastfeeding while you and pēpi are still finding your rhythm, but it can happen at any stage — particularly when feeds are skipped, when you're run down, or when there's pressure on the breast from a tight bra or a heavy bag strap. Understanding mastitis as inflammation first matters, because it shapes how we care for it: gently, rather than aggressively.

The signs to watch for

Mastitis tends to come on quickly, often within a few hours. You might notice:

• A firm, swollen or wedge-shaped area in one breast that's tender or painful
• Redness or a warm patch over that area
• Breast pain while feeding or between feeds
• Flu-like symptoms — fever, chills, shivering, body aches and fatigue
• Feeling suddenly and unexpectedly run down

Those flu-like symptoms are the part that catches many mums off guard. If you feel like you're coming down with something and you have a sore, hot spot on your breast, think mastitis — and don't wait it out hoping it passes on its own.

Gentle care that actually helps

Current thinking on mastitis has shifted in recent years. Where mums were once told to massage firmly and "empty" the breast at all costs, the guidance now leans toward gentle, anti-inflammatory care — because rough handling can actually make the swelling worse. Health New Zealand and the New Zealand College of Midwives both emphasise keeping milk moving comfortably while calming the inflammation, rather than forcing the breast to drain.

Here's what tends to bring relief:

• Keep feeding as normally as you can. It's safe to keep breastfeeding pēpi from the affected side — your milk is not harmful to baby, and regular, comfortable feeding helps keep things moving.
• Feed or express only to comfort. You don't need to drain the breast completely. Aim for relief, not emptiness.
• Cool, not hot. A cool compress or a chilled cloth between feeds can ease swelling and pain. Many mums find cold far more soothing than heat once inflammation has set in.
• Gentle touch only. Light stroking toward the armpit (lymphatic-style) is far kinder than deep, firm massage.
• Rest and fluids. Mastitis is your body asking you to slow down. Get into bed with pēpi, drink plenty of water, and let the washing wait.
• Pain relief. Your midwife or pharmacist can advise on anti-inflammatory pain relief that's compatible with breastfeeding.

Through all of this, looking after the skin of your nipples matters too. Cracked or grazed nipples can be a doorway for infection, so keeping them soft and protected is part of prevention. A little organic nipple butter after feeds helps soothe and protect tender skin — and because it's plant-based and lanolin-free, it's safe for pēpi and there's no need to wipe it off before the next feed.

Comfort and prevention between feeds

While you're healing, staying dry and comfortable makes a surprising difference. Damp pads against sore skin can add to the irritation, so changing breast pads regularly and letting your skin breathe is worth the effort. Soft, breathable organic cotton and wool breast pads are gentle against inflamed skin and naturally wick moisture away, which helps keep the area dry between feeds. Choosing well-fitting, non-restrictive clothing — and skipping the underwire for now — also takes pressure off the breast while it recovers.

Many mums find that a relaxed, unhurried feed helps too. Settling somewhere quiet, getting comfortable before pēpi latches, and checking that the latch feels deep and pain-free can all reduce the strain on your breasts over time. If feeding consistently hurts, that's worth raising with your LMC or a lactation consultant — getting the latch right is one of the best ways to prevent mastitis coming back.

When to call your midwife

This is the part that matters most. Mastitis can progress quickly, and while gentle home care resolves many cases, some need treatment. Health New Zealand advises contacting your midwife, doctor or Healthline (0800 611 116) if:

• Your symptoms don't improve within about 24 hours of gentle care
• Your symptoms are getting worse, or your fever is climbing
• You feel very unwell, or the redness is spreading
• You notice a hard, painful lump that isn't easing
• There's pus, or a cracked nipple that looks infected

Your midwife may prescribe antibiotics if an infection is present — and if so, it's important to finish the full course even once you feel better. Reaching out early isn't an overreaction; it's exactly what your LMC is there for, and it can stop a manageable case from turning into something more serious like a breast abscess. Trust your instincts. If something feels wrong, make the call.

Be gentle with yourself, mama

Mastitis can knock you flat — physically and emotionally — especially in those tender early weeks when you're already tired and finding your feet. Please know it's not a sign you've done anything wrong. It's common, it's treatable, and with rest, gentle care and the right support, the vast majority of mums come through it and carry on breastfeeding happily.

Be kind to yourself. Lean on your whānau, let the housework slide, climb back into bed with your baby, and give your body the quiet it's asking for. And if you're ever unsure, your midwife is only a phone call away — that's what the village is for.
