Nipple pain almost always has a fixable cause, whether it’s a breastfeeding latch problem, friction from clothing, a hormonal shift, or an infection. The right fix depends on what’s triggering the pain, so identifying the cause is the first step toward relief. Here’s a practical guide to the most common causes and what actually helps.
Fix a Shallow Latch First
The most common reason for nipple pain during breastfeeding is a shallow latch, where the baby suckles only on the nipple instead of taking in a good portion of the areola. A proper latch means your baby’s mouth covers not just the nipple but about 1 to 2 inches of the areola, and asymmetrically: more of the lower areola should be in their mouth than the top.
Getting there takes some setup. Bring your baby close so their ear, shoulder, and hip form a straight line, and bring the baby to your breast rather than leaning your breast toward them. Hold your breast in a C-shape behind the areola, like you’re holding a sandwich. Point your nipple toward the baby’s nose and let it brush their upper and lower lip until their mouth opens wide, like a yawn. Then guide your breast in so the nipple aims toward the roof of their mouth.
You’ll know the latch is working when their mouth is wide open, their chin rests against the lower breast, you can see some areola above their upper lip, and you don’t feel pain. If their mouth only covers the nipple, you can see most of the areola, and it hurts, gently break the suction with your finger and try again. A single feeding with a corrected latch can make a noticeable difference in comfort.
Protect and Moisturize Between Feedings
Once latch is addressed, the tissue still needs time to heal. Lanolin ointment applied right after nursing provides immediate moisture to cracked or raw skin, and about 82% of lactation consultants recommend it for that purpose. Silver nursing cups, small caps worn between feedings, offer a different approach: they create a protective barrier that keeps the nipple from rubbing against fabric. Surveys show about 85% of mothers using silver cups report noticeable improvement within 3 to 5 days.
Many lactation consultants suggest using both together. Apply a thin layer of lanolin or coconut oil right after nursing for moisture, then place silver cups over the nipple between sessions for ongoing protection. This combination addresses both dryness and friction at the same time.
One thing to skip: salt water soaks. Despite their popularity as a home remedy, soaking nipples in salt water, Epsom salts, or diluted chlorine solutions actually breaks down the skin and can create open wounds. The same goes for air-drying nipples with a hairdryer. Moist wound healing, not drying, is what damaged nipple tissue needs.
Recognizing Thrush vs. Bacterial Infection
If nipple pain persists despite good latch and moisturizing, an infection may be involved. Thrush (a yeast infection) and bacterial infections feel and look quite different, and they require different treatments.
Thrush typically causes burning, shooting, or needle-like pain that often worsens after a feeding rather than during it. Your baby may have white patches inside their cheeks or lips, though not always. A white coating on the tongue alone is usually just a normal “coated tongue” and doesn’t confirm thrush. If you have a history of recurrent vaginal yeast infections, you’re more likely to develop nipple thrush.
Bacterial infections look different. The hallmarks are yellow crusting or discharge on the nipple, usually accompanied by visible cracks or skin damage. This kind of infection is treated with antibiotic ointments or oral antibiotics, while thrush calls for antifungal treatment. Getting the right diagnosis matters because treating one won’t help the other.
Vasospasm: When Cold Makes It Worse
If your nipple turns white, then blue or purple, then red after feeding or cold exposure, and the pain feels like an intense burning or throbbing, you’re likely dealing with vasospasm. This happens when blood vessels in the nipple constrict and cut off blood flow temporarily, similar to Raynaud’s phenomenon in fingers and toes.
Warmth is the immediate remedy. Apply a warm compress right after feeding and avoid exposing your chest to cold air. Keeping your core warm helps too. For persistent vasospasm, magnesium supplements (300 to 600 mg daily) can help relax the blood vessels. Some people find that avoiding caffeine and nicotine, both of which constrict blood vessels, also reduces episodes.
Tongue Tie and Pump Fit
Two mechanical causes are worth checking if pain doesn’t resolve. Tongue tie (ankyloglossia) restricts the baby’s tongue movement and prevents a deep latch no matter how carefully you position them. A trained provider can assess this and, if needed, release the tissue with a quick procedure.
Breast pump trauma is surprisingly common and often overlooked. If pumping hurts, the flange (the cone-shaped piece that fits over your nipple) may be the wrong size, or the suction may be set too high. Having someone observe a pumping session and adjust the fit can eliminate a pain source you might not have suspected.
Exercise-Related Nipple Pain
Runner’s nipple is caused by repeated friction between fabric and skin, especially during long runs or workouts. The fix is straightforward: reduce the friction. Wear soft, well-fitting clothing made of semi-synthetic or silk-type fabrics, and avoid shirts with rubberized logos or screen prints that create extra abrasion. Applying petroleum jelly or a lubricating balm directly over the nipples before exercise creates a protective layer. Adhesive bandages or small circular pieces of athletic tape work as a mechanical barrier and are a go-to solution for runners. Women benefit from bras made of semi-synthetic material that fit snugly without shifting.
Hormonal Nipple Pain
Cyclical breast and nipple tenderness tied to the menstrual cycle is extremely common and typically peaks about a week before your period, then resolves once your period starts. This pattern repeats monthly and is driven by natural fluctuations in estrogen. Pregnancy amplifies this effect significantly as estrogen levels rise.
Magnesium supplements taken during the two weeks before your period can help ease cyclical breast tenderness. A well-fitting, supportive bra during the sensitive window also reduces discomfort from movement. If the pain follows this predictable cycle and doesn’t come with any visible skin changes or lumps, it’s almost certainly hormonal.
Skin Conditions That Mimic Other Problems
Eczema on the nipple or areola causes itchy, red, sometimes flaky patches that can easily be mistaken for thrush. The distinction matters because eczema responds to moisturizers and mild steroid ointments, not antifungals. Psoriasis can also affect the nipple area with similar-looking lesions. If you have eczema or psoriasis elsewhere on your body and develop nipple irritation, the skin condition is the more likely explanation. Reducing triggers like harsh soaps, fragranced products, and rough fabrics often helps.
When Nipple Pain Needs Urgent Attention
Most nipple pain has a benign, treatable cause. But certain signs warrant prompt evaluation. Redness or flaky skin on the nipple that doesn’t improve with treatment, nipple discharge (especially blood) that isn’t breast milk, a nipple that starts pulling inward, a new lump in the breast or armpit, dimpling or thickening of breast skin, or any unexplained change in breast size or shape are all warning signs the CDC lists for breast cancer. Paget’s disease of the nipple, a rare form of breast cancer, can mimic eczema with persistent flaking and crusting that doesn’t respond to standard skin treatments. These symptoms can also have noncancerous explanations, but they need to be evaluated rather than watched.
