Sore Nipples While Breastfeeding: Why It Happens and How to Find Relief
Last updated: July 2026 — Reviewed by the Mumsy Natural content team using current, publicly available breastfeeding health resources. This article is for general information only and is not a substitute for medical advice. Please consult your doctor or a certified lactation consultant (IBCLC) about your specific situation.
Quick answer: Sore nipples during breastfeeding are usually caused by a shallow latch, nipple cracks or dryness, engorgement, a clogged duct, thrush, or — less often — mastitis or nipple vasospasm. With a good latch and consistent care, most nipple soreness starts to ease within the first one to two weeks. If the pain is severe, doesn’t improve, or comes with fever, bleeding, or redness, it’s time to check in with a healthcare provider.
If you’ve ever typed “why do my nipples hurt when I breastfeed” or “how do I get my nipples to stop hurting” into your phone at 3 a.m., you are absolutely not alone. This guide walks through the real causes, what actually helps, and when a symptom means it’s time to call for backup.

1. Why Do Nipples Hurt During Breastfeeding?
Some tenderness in the first days of nursing is common — your skin and your baby are both learning. But breastfeeding pain generally falls into two categories, and telling them apart matters:
- Localized nipple pain: Usually tied to latch, friction, or dry/cracked skin.
- Deeper breast pain or fullness: Usually tied to engorgement, a clogged duct, or — if it comes with fever or flu-like symptoms — mastitis, which needs medical attention.
Mild soreness that fades within a minute of latching, especially in the first couple of weeks, is considered normal. Pain that’s sharp, constant, or lasts through the whole feed is a sign something needs adjusting.
2. Common Causes of Nipple Pain (In Detail)
A Shallow or Incorrect Latch
This is the single most common cause of nipple pain. When a baby latches onto the nipple alone instead of taking in a good mouthful of areola, the nipple gets compressed and rubbed with every suck — which quickly leads to soreness and, over time, cracking. Tongue-tie or other anatomical differences in the baby’s mouth can also make a deep latch harder to achieve.
Cracked or Dry Nipples
Repeated friction, a poor latch, harsh soaps, or staying in a damp nursing pad too long can all strip away the nipple’s natural moisture barrier, leading to dryness, chapping, and cracks.
Engorgement and Clogged Ducts
When your milk comes in, breasts can become full and firm, which can make it harder for your baby to latch deeply — adding extra strain on the nipple. A firm, tender spot in the breast may signal a clogged duct.
Thrush (Yeast Infection)
Itching, shiny or flaky skin, and a burning pain that continues after the feeding ends can point to a yeast infection. If your baby also has white patches inside their mouth, both of you typically need treatment at the same time.
Mastitis
An untreated clogged duct can progress to mastitis — breast tissue inflammation that shows up as redness, warmth, swelling, fever, and flu-like symptoms. This requires prompt medical evaluation.
A Less Common Cause: Nipple Vasospasm
Some mothers experience a sharp, burning pain along with a color change in the nipple (white, then blue or red) — often triggered by cold. This is caused by a temporary narrowing of the blood vessels in the nipple. It’s less common than the causes above, but real, and worth mentioning to your provider if you notice it.
3. How to Relieve Sore Nipples While Breastfeeding
- Fix the latch first. This is the most effective long-term fix. A lactation consultant (IBCLC) can watch a feeding and make small adjustments that make a big difference.
- Soften the breast before latching. If you’re engorged, hand-expressing a little milk before the feed can make it easier for your baby to latch deeply.
- Use a nipple cream or barrier ointment. A fragrance-free, natural formula helps lock in moisture and support the skin barrier while it heals.
- Try cold or warm compresses. Cold can ease engorgement pain; warmth may help with a clogged duct.
- Keep nipples dry between feeds. Change damp nursing pads often — trapped moisture slows healing.
- Expressed breast milk is a traditional remedy some sources mention, though the evidence on how much it actually helps is mixed. If you’re using a nipple cream, it’s generally best to follow that product’s own instructions rather than layering remedies.
- Choose breathable, well-fitting bras and pads, and skip anything that rubs or traps heat.
- Skip soap, alcohol wipes, and other harsh cleansers on the nipple area — plain warm water is enough.
4. How Long Do Cracked Nipples Take to Heal?
With a corrected latch and consistent care, nipple soreness typically starts improving within the first few days to two weeks. Healing time varies from person to person. If pain hasn’t improved in that window, is getting worse, or cracks are deepening, it’s worth having the underlying cause (latch, thrush, mastitis) properly evaluated rather than waiting it out.
5. When to Call Your Doctor or a Lactation Consultant
Reach out to a healthcare provider (your OB-GYN, your baby’s pediatrician, or a certified lactation consultant) if you notice any of the following:
- Pain that’s severe or isn’t improving after a couple of weeks
- Bleeding or a deepening crack
- Redness, warmth, swelling, or fever (possible mastitis)
- A burning pain that continues after the feed ends (possible thrush)
- Any concerns about your baby’s latch, weight gain, or feeding pattern

6. How to Choose the Right Nipple Cream
With so many nipple creams on the market, here’s what’s worth looking for:
- Clean, transparent ingredients — no parabens, alcohol, or synthetic fragrance
- Wipe-off requirements — some lanolin-based balms need to be removed before nursing; plant-based formulas often don’t, which is simpler in practice
- Independent or dermatological testing, especially for sensitive skin
- A texture that absorbs well rather than sitting on the skin
- Pump compatibility, if you use a breast pump regularly
One product that meets these criteria is Mumsy Natural® Nipple Care Cream:
- Recognized by the Habitat Association and Alarko Holding, with a 100% natural, certified organic formula
- Free of lanolin, parabens, alcohol, and fragrance; built on organic shea butter, jojoba, and beeswax
- No need to wipe off before nursing
- Compatible with breast pumps
- Used and recommended by OB-GYNs, pediatrist, midwives, and lactation consultants
7. Frequently Asked Questions
Why do my nipples hurt when I’m breastfeeding? The most common cause is a shallow latch, where the baby compresses and rubs the nipple instead of taking in a full mouthful of breast tissue. Dry or cracked skin, engorgement, thrush, and — less often — mastitis can also cause pain.
How do I get relief from sore nipples while breastfeeding? Start by having your latch checked. Beyond that, a natural nipple cream, keeping nipples dry between feeds, and cold or warm compresses (depending on the cause) can all help.
How long do sore or cracked nipples take to heal? Most soreness improves within the first few days to two weeks once the latch is corrected. Pain that persists or worsens should be evaluated by a provider.
Is nipple pain always a sign of mastitis? No. Mastitis comes with redness, warmth, swelling, and fever. Ordinary soreness is more often related to latch or dry skin.
Is breastfeeding supposed to hurt? Mild tenderness in the first couple of weeks is common, but breastfeeding shouldn’t be sharply or constantly painful. Ongoing pain is a signal to check the latch or rule out an underlying cause.
Should I use a lanolin-based cream or a plant-based one? Both are used widely. Lanolin has a long track record, though some people are sensitive to it or dislike its smell and taste (which can matter to a nursing baby). Plant-based, fragrance-free formulas are a common alternative for mothers who prefer to skip lanolin.
8. The Bottom Line
Sore nipples are one of the most common breastfeeding challenges, and in most cases they improve quickly with a better latch, consistent care, and the right product. If pain lingers or infection symptoms show up, don’t wait it out — a lactation consultant or your doctor can help you get back to comfortable feeds.
