Mastitis and breastfeeding problems
what has changed in the advice
Most breastfeeding problems trace back to how the baby attaches, and most are fixable with the right help rather than by stopping. The guidance on mastitis in particular has changed substantially in recent years, and some of the advice still widely given now appears to make things worse.
Seek help the same day if you have
- a fever with shivering, feeling like flu, and a red painful breast
- a firm, exquisitely tender lump that is worsening — this may be an abscess
- rapidly spreading redness, or a wound with pus
- no improvement after 12 to 24 hours of feeding and simple measures
- you feel seriously unwell, confused, or cannot care for your baby
Untreated mastitis can progress to an abscess needing drainage. If you feel systemically unwell rather than simply sore, that is the point to be seen rather than to wait. In an emergency call 999, or go to the Royal London Hospital Emergency Department, Whitechapel Road, London E1 1FR.
Do not deep massage an inflamed breast
Vigorous massage, aggressive pumping and hot compresses were standard advice for years. Current understanding is that mastitis is inflammation and swelling of the ducts rather than milk 'stuck' in one place, and that forceful massage worsens the swelling and tissue damage. Instead: ice, not heat, for the inflammation; gentle lymphatic stroking towards the armpit rather than deep pressure into the breast; and feeding normally rather than emptying the breast as completely as possible.
Managing mastitis
- Keep feeding on both sides, as normal. The milk is safe for your baby. Stopping abruptly makes it worse.
- Feed to comfort, not to empty. Over-draining signals the breast to make more milk and perpetuates the cycle.
- Cold packs for 10 to 15 minutes after feeds to reduce swelling and pain.
- Anti-inflammatories — ibuprofen and paracetamol, both safe while breastfeeding — taken regularly.
- Rest and fluids, and support the breast with a well-fitting, non-restrictive bra.
- Review the attachment, since poor drainage from a shallow latch is the usual underlying cause.
Antibiotics are needed if you have a fever and feel unwell, if there is a cracked nipple with visible infection, or if there is no improvement after 12 to 24 hours. Most mastitis is inflammatory rather than bacterial at the outset, which is why the first day is managed without them.
Other common problems
- Sore or cracked nipples — almost always attachment. Pain beyond the first few seconds of a feed is a sign to get the latch checked, not to endure it. A purified lanolin or your own expressed milk helps healing.
- Blocked duct — a tender lump without fever. Feed normally, gentle stroking, cold packs. It usually clears in a day or two.
- Engorgement in the first week — feed frequently, express just enough for comfort, cold packs between feeds.
- Thrush — burning or shooting pain during and after feeds with shiny or flaky nipples. Mother and baby must be treated together, or it bounces back and forth.
- Vasospasm — nipples blanching white then purple after feeds, with intense pain. Keep warm, avoid cold exposure.
- Low supply — genuine low supply is uncommon. Judge by wet nappies and weight gain, not by how full you feel or how much you can pump.
Tongue tie
A restrictive tongue tie can prevent a deep latch and cause persistent nipple pain, poor transfer and slow weight gain. It is worth an assessment by someone experienced if feeding remains painful despite positioning help — but it is also over-diagnosed, and division is not the answer to every feeding difficulty.
Getting help early
The single most useful intervention in breastfeeding difficulty is a skilled person watching a whole feed. Most problems are positional and are solved in one session. If feeding hurts, or your baby is not gaining as expected, ask early rather than after weeks of struggling — and note that deciding to stop, or to combination feed, is a legitimate choice rather than a failure.
Book an appointment if you have a red painful breast with fever, persistent nipple pain, or concerns about your baby's weight. We can assess and treat mastitis the same day, weigh and examine your baby, and arrange feeding support.
