Pain: if breastfeeding hurts

Pain in your nipples or breasts whilst breastfeeding is most often linked to how you are holding your baby and bringing them to your breast (often referred to as positioning and attachment). Before considering any alternative reasons for experiencing pain whilst breastfeeding please use our guide to positioning and attachment to rule this out as a cause of pain. Even if there is another medical basis for the pain, getting positioning and attachment as comfortable as possible will still help.

When you first start breastfeeding, it is common to experience a strong and sometimes uncomfortable sensation for the first few seconds of your baby latching on. However, this should pass quickly, and feeding should become comfortable. If this is not the case, trying some small changes to your positioning and attachment could help make feeding more comfortable for you.

If the pain is not improved after trying some of the ideas in our guide on positioning and attachment, please seek support from a breastfeeding supporter. They can observe and assess a full feed. You can also find a local support group here or contact the National Breastfeeding Helpline.

If your nipple is damaged, use moist wound healing within the wound (avoid applying cream to whole nipple) to stop a scab forming, which will deepen the wound. You can continue to breastfeed on a damaged nipple as it will still be able to heal, but it is very important to get support with positioning and attachment to prevent further damage occurring.

If a breastfeeding practitioner has helped you adjust your positioning and attachment and you still have pain or nipple damage, your baby may need to be assessed for a tongue tie or other issues that might be making breastfeeding harder.

Other causes of pain in breastfeeding:

Allergy

If your nipples are itchy (which may be triggered by warmth) or changed in colour (which may show as redness on lighter skin tones) but you do not see any change in the shape of your nipples and are not experiencing pain, the problem may be an allergy to something in contact with your nipples, such as nipple cream or breast pads. Try eliminating these to identify the cause. If disposable breast pads are causing irritation, you could try washable ones instead.

The symptoms may be relieved by a non-sedating antihistamine and hydrocortisone 1% cream applied sparingly. See our factsheet on antihistamines for more information on taking these whilst breastfeeding.

Vasospasm

If your nipple turns white at tip after breastfeeds and pain or itchiness, and redness on some skin tones, occurs immediately at end of feed when blood returns, vasospasm could be the cause.

This is due to restricted circulation from compression of the nipple by the baby squashing it between their tongue and the roof of their mouth during a feed. It can be relieved by help with attachment from a specialist breastfeeding practitioner. Vasospasm can occur in one or both breasts. It does not respond to medication which is unnecessary, but can be improved by adjusting positioning and attachment.

Raynaud’s Phenomenon

If the pain is worst at the end of or after a feed and your nipples change colour rapidly after breastfeeds from white to purple then red (this might not be visible on all skin tones), you may be experiencing Raynaud’s Phenomenon.

If you have a history of circulation problems or migraine and pain is triggered or made worse by cold, Raynaud’s Phenomenon is more likely. Pain can be immediately after a feed but may also be delayed or can be triggered by cold even when not feeding.

You may be able to improve your symptoms by avoiding breastfeeding in cold places, covering your nipple as soon as a feed is finished and applying warmth after feeds. If this is not effective, consider asking GP to prescribe nifedipine 10mg three times a day or nifedipine LA 30mg daily. Treatment for two weeks may be sufficient or may be needed long term. You can find more detail in our Raynaud’s phenomenon factsheet.

A white spot, bleb or blocked nipple pore.

If pain is worst at the end of or after a feed and you can point to a discrete spot (which may be white, yellow or pale pink) on your nipple as the origin of the pain, this is likely to be due to a white spot, also called a bleb, blocked nipple pore or milk blister. Symptoms may return periodically.

Blebs are thought to be a surface presentation of underlying inflammation, so they are best treated with anti-inflammatory measures. They may also be caused pressure or rubbing whilst you are feeding, so it’s a good idea to get support with positioning and attachment. 

You can continue to feed with a bleb, and feeding may help it to clear spontaneously. If you are in pain, you can take pain relief, such as paracetamol or ibuprofen (see our factsheet on pain relief for more information). You could also try a warm or cool compress after feeding. If the bleb does not clear, speak to a healthcare professional. They may be able to prescribe a steroid cream that could help.

Some sources suggest that having a healthcare professional de-roof (take the top layer of skin off) your bleb or blister with a sterile needle can provide relief, as milk that has accumulated behind it can be released. However, others say that this is unnecessary and could cause further inflammation. It is not recommended that you attempt to de-roof a bleb yourself, with a needle or by picking, squeezing or rubbing it, as this could make it worse or allow infection in. If you do have your bleb de-roofed by a healthcare professional, feeding frequently from that breast afterwards may help stop it forming again.

Expressing milk

If your nipple is sore or damaged and you are using a breast pump rather than feeding directly, you may need to reduce the strength of the suction on your pump or you may be using a flange that is the wrong size.  Speak to your health visitor, midwife or peer supporter to get support with expressing your milk if needed.

Strong let-down

If the pain is strongest at start of feed or just before a feed and there is a sharp intense pain in your breast(s), often described as squeezing pain, this can be due to the let down or milk ejection reflex. Pain can be worse on fuller breast.

If it is associated with leaking milk, you can reduce this by applying firm hand pressure to your breast at the time of leaking.

If your baby also makes a clicking noise during feeds or pulls away choking once the feed has started, the fast flow of milk may mean your baby is struggling to attach well. Further support from a skilled breastfeeding practitioner to improve attachment may be useful.

You may find it helpful to express a small amount of milk just before a feed if your breasts are full, to get past the powerful let-down before starting the feed, or to use a laid-back breastfeeding position, so that the milk flow is less overwhelming for your baby.

Engorgement

If your breasts are painfully hard and full, and feeding or expressing milk relieves this sensation, your breasts may be engorged. This may be worst first thing in the morning, especially if you have not fed frequently through the night. You can avoid engorgement by feeding frequently and responsively, including at night time. Consider offering your baby a feed whenever your breasts start to feel full or uncomfortable. If you are unable to feed at that time, or if your baby refuses a feed, you can express just enough milk to relieve the discomfort. Avoid expressing more milk than necessary, as this could trigger an increase in your milk supply and make the engorgement worse. Allowing your breasts to remain engorged could lead to your breasts becoming inflamed (mastitis), or a reduction in your milk supply, so it is best to avoid this whenever possible.

If you find it hard to latch your baby on when your breasts become very full, you may like to try reverse pressure softening. Reverse pressure softening is a way to soften your areola. It can help make latching and removing milk easier when your areola is very swollen and engorged by temporarily relieving firmness and swelling.

It can be particularly helpful if you have some oedema or swelling due to IV fluids or drugs given during labour and birth, especially if you had a caesarean section. Breast engorgement in the early days can be caused by your milk coming in or by a combination of fluid held in the breast tissue around the milk ducts as well as by milk within the breast.

Reverse pressure softening briefly moves mild or firmer swelling away from under your areola, slightly backward into your breast for a short period of 5-10 minutes.   This allows your areola to change shape and makes latching easier as your baby is able to get more of your areola and breast tissue into their mouth.

Reverse pressure softening also causes a ‘let-down’ reflex, making it easier for your baby to get milk or for you to remove milk by hand expressing or expressing with a breast pump.

Reverse pressure softening should not be used if you have mastitis, plugged ducts or a breast abscess.

Blocked ducts and Mastitis

If there is a sore, lumpy area on your breast that may also feel hot and can appear red on lighter skin tones, you may have a blocked duct or mastitis. Mastitis is an inflammation of the breast. It may be accompanied by flu-like symptoms. Continue to feed responsively and seek support from a specialist breastfeeding practitioner as soon as possible.  Blocked ducts or mastitis may be triggered by feeding infrequently, allowing your breasts to become overfull or other situations that increase pressure on your breast, for example, wearing a bra that is too tight or wearing your baby in a sling for longer than usual. Adjusting the way you hold your baby and bring them to your breast when feeding (positioning and attachment) may also help.

You can take ibuprofen 400mg as anti-inflammatory if appropriate (i.e. if you have no contra-indications such as asthma or stomach ulcer), and also paracetamol for pain or fever.  Antibiotics are not usually required if self-help measures are started quickly, but you should see a doctor if your symptoms persist. You can read our factsheets on pain relief medicines and breastfeeding and our mastitis page for more detailed information.

Abscess

An abscess is a rare complication of mastitis. You might want to consider whether you have an abscess if mastitis has not resolved following frequent, effective feeding and a course of antibiotics and if the skin on your breast looks like orange peel.  A milk sample should be taken to ascertain the micro-organism involved in the infection to help decide which antibiotic might be most appropriate. An ultra sound investigation may be required to diagnose an abscess. Drainage of pus by needle aspiration or surgical drainage together with appropriate antibiotic might be offered. Abscess formation is a rare complication of infectious mastitis and may involve MRSA. You may benefit from emotional support from a breastfeeding supporter alongside specialist support from medical staff.
