Nipple Vasospasm: White Nipples and Burning Pain After Feeds

What it feels like

The pattern is distinctive once you know it. During the feed, things may be fine or only mildly uncomfortable. When your baby comes off, the nipple turns white — sometimes with a clear line where the colour stops — and then over the next minute or two it flushes back to pink or purple. As the blood returns, the pain arrives: burning, stabbing or shooting, sometimes deep in the breast. La Leche League GB describes it as being a bit like the pins and needles you get after sitting on your foot.

It is often worse in the cold — stepping out of a shower, going outside, opening a fridge — and worse at night.

Why it happens

La Leche League GB is direct about the usual cause: the main cause of nipple vasospasm is a shallow latch. If the nipple is squashed against the roof of your baby's mouth during feeding, blood flow is constricted, and the pain comes when it returns. The tell is what the nipple looks like as it comes out of your baby's mouth — creased, flattened, or wedge-shaped like a new lipstick rather than round.

The second cause is Raynaud's phenomenon, a circulatory condition where small blood vessels constrict in response to cold. The HSE describes it affecting the fingers and toes, with the affected area turning white and sometimes cold, and its guidance on sore nipples notes that a small number of mothers have vasospasm because of Raynaud's. If you have always had white, painful fingers in cold weather, that is the likely background, and symptoms may happen away from feeding too.

Vasospasm or thrush?

La Leche League GB notes that nipple vasospasm is sometimes misdiagnosed as thrush, and this matters because the treatments are opposite in one important respect.

• Vasospasm. Pain comes after the feed, with visible colour change — white, then red or purple. Triggered or worsened by cold. Warmth relieves it. Often one side, or worse on one side.
• Thrush. Pain usually during and after feeds, often both sides, with pink, shiny or flaky nipples and shooting pain deep in the breast, typically after a period of pain-free feeding. Cold may feel soothing. Your baby may have oral thrush.

If treatment for thrush has not worked, vasospasm is one of the first things to reconsider. NICE's Clinical Knowledge Summary on breastfeeding problems covers the differential diagnosis of nipple pain, and is a reasonable thing to ask your GP to look at with you.

What helps

The most important intervention is fixing the cause. La Leche League GB puts it plainly: helping your baby take a bigger mouthful of breast can often solve the problem. Get a face-to-face latch assessment from a midwife, health visitor, public health nurse, infant feeding team or IBCLC lactation consultant, and ask about tongue tie if the latch will not improve.

For the pain in the meantime:

• Dry heat straight away. LLLGB suggests applying dry warmth — a warm wheat bag or hot water bottle — to the nipple as soon as your baby comes off.
• Cover up fast. Get your bra and top back on before the cold hits.
• Cup the nipple in a warm hand, or hold your baby close against the breast.
• Gentle massage of the nipple with your fingers, using a little edible oil such as olive oil so your fingers glide.
• Keep your whole body warm. Warm feet and hands help; vasospasm is a circulatory response and it is not confined to the nipple.
• Avoid cold compresses on the nipple. This is where standard nipple-pain advice goes wrong for vasospasm — cold is the trigger, not the treatment.
• Cut down on caffeine. LLLGB notes caffeine can make Raynaud's worse.
• Stop smoking if you smoke, as nicotine constricts blood vessels.

Medicines

Where vasospasm is severe and persistent and the latch has been addressed, a calcium channel blocker such as nifedipine is sometimes prescribed, and it is used in breastfeeding. That is a decision for your GP, and we do not give doses here. The Breastfeeding Network's Drugs in Breastmilk service can help your clinician check compatibility. Some clinicians also discuss magnesium or vitamin B6; the evidence is weak and it is still a conversation to have with a prescriber rather than to act on alone.

When to get help

• Pain at every feed, whatever it is caused by. The NHS is clear that nipple pain at every feed is a reason to ask for help.
• Nipples that crack or bleed, which raises the risk of infection.
• Pain that has not improved after the latch has been properly assessed.
• Thrush treatment that has not worked.
• Colour changes in fingers and toes as well, which points towards Raynaud's and is worth investigating in its own right.

One thing worth saying

Vasospasm is a common reason people stop breastfeeding before they wanted to, largely because it is under-recognised and because "it's just thrush" is a very sticky diagnosis. If you have been in pain for weeks and been told to persevere, that is not adequate advice. Pain is a signal that something needs changing, and it is treatable — and if, having had it properly assessed and treated, you decide you have had enough, that is a reasonable decision made with good information.

What tends to make it worse

• Cold air on a wet nipple after a shower or a feed.
• Cold compresses or gel pads applied to the nipple.
• Caffeine and nicotine.
• Stress and lack of sleep, which affect circulation.
• A pump flange that is the wrong size, which compresses the nipple in the same way a shallow latch does.

How long it takes to settle

Where the cause is a shallow latch, the colour change and the pain usually improve within days of the latch improving, though damaged skin takes longer. Where Raynaud's is involved it may recur in cold weather and can persist beyond the feeding period. Either way it does not usually mean stopping breastfeeding, and it should not be left unaddressed for months on the assumption that it is just what feeding feels like.
