Breastfeeding Pain: What to Expect + When to Seek Help

September 10, 2013

Aching, burning, bleeding, cracking, throbbing, peeling – all words you never want to use to describe your nipples or breasts! Unfortunately, many breastfeeding moms experience some sort of pain as they begin to nourish their baby. Although breastfeeding is one of the most natural things in the whole world, it isn’t always easy. Worst of all, pain can cause moms to stop breastfeeding, which is why it’s important to learn what pain means, find possible solutions, and know when to seek help.


It’s common to experience pain when you’re beginning to breastfeed your little one. This tenderness is not serious and goes away within a short time. You’re both getting the hang of a totally new thing, and it can take a little while to find your groove.

Another cause of tenderness in the first weeks after birth is changing hormones. You might even experience cramping in your uterus during the first few days of breastfeeding – this is because nursing releases the hormone oxytocin, which helps your uterus contract and slows blood loss after delivery.

Most of the time, a poor latch is the cause of nipple pain. When your baby is latched correctly, the most sensitive part of your nipple is pulled deeply into their mouth. The easiest way to identify a shallow latch is by removing your baby and checking the shape of the nipple. If the nipple looks creased or drawn into a point, your baby may be pinching with their gums.

Your baby will suck extra-hard on your breast if the milk flow is pinched off due to a poor latch, if milk supply is low, or if the nipple is hard to draw in because of engorgement. This extra strong suction applied to such a small surface area can cause blistering. Tips for healing blisters and blebs >>

Sore nipples in later months may be related to sucking pattern changes in a teething baby. Tips for handling biting and teething >>

Plugged ducts can happen if you’re not emptying your breasts completely or often enough. If you have a plugged duct, you may notice a tender bump on your breast that feels warm and swollen. Tips for treating a plugged duct >>

Experiencing pain when using a breast pump? If your breast shields are too small, pumping can cause unneeded friction on your nipples. Tips for choosing a correctly fitted shield >>


Soothe sore nipples with Medela’s Tender Care Lanolin and Hydrogel pads, which are both safe for mom and baby.

Avoid bras made from synthetic materials – cotton is the most breathable and skin-friendly fabric. Keep bra pads and bras dry and allow air to circulate around your breasts whenever possible.

Multiple-hole breast shells like our SoftShells can help protect from further irritation by holding fabric off of sore nipples and allowing for better air circulation.

A nipple shield, when used under the guidance of a lactation professional, may also help you establish a good latch and help you continue breastfeeding.

Use your own milk – breast milk has healing properties and just a few drops can soothe cracks or other irritations.

Breastfeed on the least sore side first – babies tend to suck harder on the first breast, but fall into a more gentle rhythm in the later part of their feeding. Hungry babies also nurse vigorously, so make sure you’re breastfeeding frequently.


Pain between feedings, pain that continues over the course of an entire feeding, or pain that lasts beyond a week means you should reach out to your health care provider or a Lactation Consultant.

Mastitis, an infection of the breast tissue, is a common but sometimes serious issue. Moms with mastitis typically notice swelling, redness, and pain, accompanied by flu-like symptoms such as nausea, fever, and sometimes vomiting. If you think you might have mastitis, contact your healthcare provider right away.

Injured nipples may also become infected with bacteria or yeast, which can slow healing and cause pain even when positioning and latch are corrected. A common yeast infection known as thrush can cause redness, irritation, or shooting pain in your nipples. If you suspect you or your baby have a thrush infection, contact your healthcare provider.

Soreness can also be caused by a tongue-tied little one. Tongue-tie is a medical condition in which the movement of the tongue is restricted by the band of tissue connecting the tongue to the floor of the mouth being too short and tight. Your doctor or a Lactation Consultant can help identify and treat tongue-tie.

Skin conditions like eczema or psoriasis or an allergic reaction to a lotion, soap, medication, or other product can also cause soreness. Your doctor can help you determine if an allergic reaction or skin condition is the cause of your pain.

  1. Hi guy’s

    I can’t seem to get my son to attach properly , and I am starting to get really cracked nipples and they’re starting to bleed a little. What can I do? As I’ve tried everything such as shieldsand expressing and I really like to breastfeed. Also he was born with a tounge tie but the doctor sorted that, but is there a possibility that could be the reason? I also have inverted nipples but they do come out once he’s sucking

  2. My daughter is now 3 months old. She has been a good eater and latches well since birth. My LC said I have extra production of milk so I have pumped the extra since the first week of her birth. I am back to work and pump (on the lowest setting) 2-3 times while at work and BF exclusively when I’m home with baby. My nipples started getting irritated and bleeding about 6 weeks after due to pumping. My LC said I needed larger shields, I am now using the XL 36 mm shields while pumping and my nipples still swell and rub along the sides. She also provided the Soft Shells to me so they could heal up faster. This seemed to help get air circulation and to dry them out but for some reason the shells cause my nipples to swell even more.

    I use lanolin while pumping to give some lubrication on the nipple. I then developed mastitis in one breast at about 3 months. I believe it was caused from the open cracks and irritation that still persists from pumping. I’ve used the nipple shields while feeding, however baby does not eat well with it on. I have put breastmilk, lanolin, and now aquapher on to help heal them up and nothing has helped. It seems as if my nipples get a little better on the weekends and then just get worse during the week while I am pumping at work.

    I am not sure what else I can do to resolve the constant pain and cracked, bleeding nipples. Any suggestions?

    I got my new medela pump today and my breast seem to be fine
    I started pumping 2 breast and then I noticed I got more milk in the left side so I decided to pump just that side but after that my breast got engorged and I would like to know if my pump might pushed air into my breast. Because eve though I put the cap on the other side I could still hear like free air. Please help

  5. My 2 months baby doesn’t like suckling.. he always stops after 5 mins and cries however when i offer him a pumped breast milk he doesn’t have a problem. So I am inly pumping now. Does the pump reduce the milk supply, as i heard that if i am only pumping the milk stops after couple of months. ( i am using medela symphony)

    • Hi – Exclusively pumping for your little one will not effect your milk supply in any way. Here’s a blog that provides some tips on how to help your baby latch successfully: Also, a breast shield can be helpful when breastfeeding because it helps your baby create suction and position the nipple in a way they may not yet be strong enough to do.
