A nipple fissure is a small crack, split, or sore area in the skin of the nipple. It sounds tiny, and sometimes it is, but anyone who has had one knows the truth: a little crack in the wrong place can feel like it has filed a formal complaint against your entire nervous system.
Nipple fissures are most common during breastfeeding, especially in the early days when a baby and parent are still learning the fine art of latch, positioning, patience, and not panicking at 3 a.m. But breastfeeding is not the only cause. Friction from running, tight clothing, eczema, dry skin, nipple piercings, pumping, infections, and certain skin conditions can also leave the nipple irritated, raw, cracked, or bleeding.
The good news: most nipple fissures improve once the cause is identified and corrected. The not-so-good news: ignoring the problem can allow pain, infection, or feeding difficulties to snowball. This guide explains the symptoms, common causes, treatment options, prevention strategies, and real-life experiences people often face when dealing with nipple fissures.
What Is a Nipple Fissure?
A nipple fissure is a break in the outer layer of skin on the nipple or nearby areola. It may look like a thin line, shallow cut, scabbed crack, raw patch, or small open wound. In breastfeeding parents, fissures often happen because the nipple is repeatedly compressed, rubbed, or pulled during feeding or pumping. In non-breastfeeding people, the same kind of skin breakdown may come from chafing, sweating, allergies, harsh soaps, or skin inflammation.
Think of nipple skin like the skin on your lips: delicate, exposed, and very unhappy when dry, rubbed, bitten, or irritated. Once the skin cracks, every touch can sting, especially during feeding, showering, exercise, or when fabric brushes against the area.
Common Symptoms of Nipple Fissure
Nipple fissure symptoms can range from mild irritation to sharp pain that makes breastfeeding, pumping, or wearing a shirt feel like a full-contact sport.
Typical signs include:
- Cracked, split, or raw-looking skin on the nipple
- Burning, stinging, or sharp pain during breastfeeding or pumping
- Scabbing, crusting, peeling, or flaking
- Bleeding from the nipple or blood spots on nursing pads
- Redness, tenderness, or swelling
- A pinched, flattened, or creased nipple after feeding
- Pain that continues after latch correction or worsens over time
Some soreness during the first days of breastfeeding can happen as the body adjusts, but severe pain, bleeding, or worsening cracks are not something to “just tough out.” Pain is information. In this case, it is usually saying, “Something needs fixing.”
What Causes Nipple Fissures?
The cause matters because treatment works best when it targets the reason the skin cracked in the first place. Applying balm without fixing a shallow latch, for example, is like mopping the floor while the sink is still overflowing.
1. Shallow latch during breastfeeding
A shallow latch is one of the most common causes of nipple fissures in breastfeeding parents. When the baby takes only the nipple instead of a deeper mouthful of breast tissue and areola, the nipple can be pinched between the tongue and hard palate. This pressure may cause pain, blanching, creasing, cracks, or bleeding.
A deep latch usually feels more like tugging than biting. If the nipple comes out flattened, lipstick-shaped, or sharply creased, latch may be the main suspect.
2. Poor positioning
Even a motivated baby can struggle if the angle is awkward. If the baby’s head is turned away, the body is not close, or the nipple is pulled sideways during feeding, friction increases. Over many feeds, that small mismatch can become a painful fissure.
3. Tongue-tie or sucking difficulties
Some babies have oral anatomy or movement patterns that make it difficult to maintain a deep, effective latch. Tongue-tie, high palate, weak suck, or jaw tension may contribute to nipple trauma. In these cases, a lactation consultant, pediatrician, or breastfeeding medicine specialist can assess feeding mechanics.
4. Breast pump problems
Pumping should not feel like the nipple is being interrogated. Flanges that are too small or too large, suction that is too high, long pumping sessions, or dry friction can irritate nipple tissue. A properly fitted flange and comfortable suction setting can make a major difference.
5. Dry skin, eczema, or contact dermatitis
Harsh soaps, fragranced lotions, laundry detergents, synthetic fabrics, adhesive nursing pads, and excessive washing can strip natural oils from the skin. People with eczema or sensitive skin may develop itching, redness, scaling, and cracks around the nipple or areola.
6. Friction from sports or clothing
Runners, cyclists, hikers, and gym-goers can develop nipple fissures from repeated rubbing against fabric, especially during sweaty workouts. This is sometimes called “runner’s nipple,” which sounds like a cartoon injury but can be genuinely painful.
7. Infection
Cracked skin can allow bacteria or yeast to enter. Signs of infection may include increasing redness, warmth, swelling, pus, fever, chills, flu-like symptoms, or worsening breast pain. Mastitis, a painful inflammation of breast tissue that may involve infection, can develop in breastfeeding people, especially when milk is not draining well.
8. Biting or teething
Older babies may clamp down during teething, distraction, or milk-flow changes. A single bite can cause a cut; repeated bites can delay healing. Babies are adorable, yes, but tiny teeth have no respect for dermatology.
How Nipple Fissure Is Diagnosed
Most nipple fissures are diagnosed through a physical exam and a discussion of symptoms. A healthcare provider may ask when the pain started, whether breastfeeding or pumping is involved, whether the nipple changes shape after feeding, what skin products you use, and whether there are signs of infection.
If breastfeeding is involved, a lactation consultant may observe a feeding session to assess latch, positioning, milk transfer, and nipple shape after feeding. If yeast, bacterial infection, eczema, psoriasis, or another skin condition is suspected, treatment may be adjusted. If a one-sided nipple rash, crusting, bleeding, discharge, or skin change does not heal, medical evaluation is important to rule out less common but serious conditions such as Paget disease of the breast.
Treatment for Nipple Fissure
Treatment has two goals: help the skin heal and stop the repeated irritation that caused the crack. Healing usually happens faster when both goals are addressed together.
Correct the latch or feeding position
For breastfeeding-related fissures, latch correction is often the most important step. Bring the baby close, align ear-shoulder-hip, wait for a wide mouth, and aim the nipple toward the roof of the baby’s mouth so the baby takes in more breast tissue. If the latch hurts beyond the first few moments, break suction gently with a clean finger and try again.
Different positions may help: laid-back nursing, football hold, cross-cradle, or side-lying. The best position is not the one that looks prettiest in a parenting brochure; it is the one where milk transfers well and your nipple does not emerge looking like it lost a wrestling match.
Use nipple-safe moisturizers
After feeding, some people apply a few drops of expressed breast milk and let the area air-dry. Medical-grade purified lanolin, hydrogel pads, or a provider-recommended nipple balm may also soothe cracked skin. Avoid products with fragrance, alcohol, menthol, or unnecessary additives, especially if the baby will feed at the breast.
Keep the area clean but not over-washed
Wash with plain water during regular bathing and avoid scrubbing. Harsh soap can dry the nipple and worsen cracking. Pat dry gently. Moisture trapped in plastic-lined pads or tight bras can also slow healing, so change damp pads often and choose breathable fabrics.
Adjust pumping technique
If pumping contributes to pain, check flange size and suction settings. More suction does not always mean more milk; sometimes it just means more pain. Lubricating the flange tunnel with a small amount of breastfeeding-safe oil or balm may reduce friction, but ask a lactation professional if you are unsure what is safe.
Manage pain safely
Cold packs may help reduce soreness after feeding, while warm compresses before feeding may soften tissue and encourage milk flow. Over-the-counter pain relievers such as ibuprofen or acetaminophen may be appropriate for many people, but anyone pregnant, postpartum, managing medical conditions, or taking other medications should ask a healthcare professional.
Treat infection when needed
If there is fever, spreading redness, pus, severe swelling, or worsening pain, contact a healthcare provider. Bacterial infections may require antibiotics. Yeast-related nipple pain may require antifungal treatment for the parent and sometimes the baby. Do not use leftover creams or random internet “miracle cures,” because the wrong treatment can irritate the skin further.
Consider temporary feeding adjustments
Many people can continue breastfeeding with cracked nipples, especially if latch is corrected and pain is manageable. If pain is severe or the nipple is actively bleeding, a short break from direct feeding on that side may be recommended while pumping or hand-expressing maintains milk supply. People with certain infections, such as hepatitis C, should ask their clinician about breastfeeding when nipples are cracked or bleeding.
How to Prevent Nipple Fissures
Prevention is mostly about reducing friction, moisture problems, and repeated trauma. Small habits can save a lot of pain.
For breastfeeding parents:
- Work on a deep latch early, ideally with lactation support if pain appears.
- Change positions if one area of the nipple keeps getting compressed.
- Break suction before removing the baby from the breast.
- Avoid letting the baby slide down to the nipple tip during sleepy feeds.
- Keep nipples dry between feeds, but do not over-wash them.
- Use correctly sized pump flanges and comfortable suction settings.
- Get help for tongue-tie, oversupply, engorgement, or recurrent plugged ducts.
For athletes and active people:
- Wear soft, moisture-wicking tops or a well-fitting sports bra.
- Apply anti-chafing balm before long runs, hikes, or rides.
- Use protective nipple covers for endurance workouts.
- Change out of sweaty clothing soon after exercise.
For sensitive skin:
- Choose fragrance-free detergent and skin products.
- Avoid harsh soaps, exfoliants, and alcohol-based products on the nipple area.
- Treat eczema or dermatitis early with guidance from a clinician.
- Wear breathable, non-irritating fabrics.
When to Call a Doctor
Most minor fissures improve within a few days once the cause is corrected. However, medical care is important if symptoms are severe, persistent, or unusual.
Seek medical advice if you notice:
- Fever, chills, body aches, or flu-like symptoms
- Increasing breast redness, warmth, swelling, or pain
- Pus, foul odor, or spreading rash
- A painful lump or suspected abscess
- Nipple cracks that do not improve after several days of care
- Severe pain during every feeding or pumping session
- One-sided nipple scaling, bleeding, inversion, discharge, or skin changes that do not heal
- Blood in breast milk that continues or concerns you
Getting help is not a sign of failure. It is maintenance. Even luxury cars need mechanics, and nipples have fewer replacement parts.
Can You Breastfeed With a Nipple Fissure?
Often, yes. Many breastfeeding parents continue nursing while a fissure heals, especially when the latch is corrected and pain is tolerable. Breast milk itself is not harmful to the baby because of a simple crack. However, if there is active bleeding, severe pain, infection, or a medical condition that changes safety recommendations, contact a healthcare provider.
If direct feeding is too painful, pumping or hand expression may help maintain supply. Use gentle settings and make sure pump parts are cleaned properly. If the baby refuses the breast because milk flow is different or the parent tenses from pain, skin-to-skin contact, relaxed positioning, and lactation support can help rebuild confidence.
Common Myths About Nipple Fissures
Myth 1: “Breastfeeding is supposed to hurt.”
Mild tenderness at the beginning may happen, but ongoing sharp pain, cracking, or bleeding is a signal that something needs attention.
Myth 2: “You just need tougher nipples.”
No. Nipples do not need boot camp. They need proper latch, less friction, and healthy skin care.
Myth 3: “All nipple cracks mean infection.”
Not always. Many fissures are mechanical injuries. Still, cracks can become infected, so worsening symptoms should be checked.
Myth 4: “More washing helps healing.”
Over-washing can dry and irritate skin. Gentle cleaning and avoiding harsh products are usually better.
Experiences and Practical Lessons From People Who Deal With Nipple Fissures
People often describe nipple fissures as surprisingly emotional. The injury is physically small, but it can affect feeding, sleep, exercise, clothing choices, body confidence, and daily mood. A breastfeeding parent may start dreading the next feeding, not because they do not want to feed their baby, but because they know the latch may bring a lightning-bolt sting. An athlete may avoid a favorite run because yesterday’s shirt turned a tiny sore into a dramatic red line. Someone with eczema may feel frustrated because the same “gentle” body wash that works everywhere else suddenly behaves like a villain on nipple skin.
One common experience is the “I thought it would go away” phase. A tiny crack appears. The person assumes it is normal, pushes through, and keeps doing the exact same activity that caused it. By day three, the fissure is angrier, the skin is scabbed, and every shower feels personal. The lesson is simple: early action matters. Fixing latch, changing a sports bra, switching detergent, lowering pump suction, or applying a protective balm early can prevent a small irritation from becoming a week-long drama.
Another shared experience is confusion over pain during breastfeeding. Many new parents hear that breastfeeding is natural, then feel guilty when it hurts. Natural does not mean automatic. Walking is natural too, but toddlers still fall over furniture. A baby may need practice, and a parent may need coaching. When a lactation consultant watches a full feeding, they may notice small details: the baby’s chin is not touching the breast, the body is twisted, the latch is shallow, or the parent removes the baby without breaking suction. These tiny corrections can produce big relief.
Pumping parents often report a different discovery: the pump was the problem. A flange that looks “close enough” may not fit well. High suction may seem efficient but can pull tissue too aggressively. Once flange size and suction are adjusted, pain may decrease quickly. Comfort is not laziness; it is part of effective milk removal.
For runners and gym-goers, nipple fissures can feel embarrassing, but they are extremely practical injuries. The solution may be as unglamorous as better fabric, anti-chafe balm, or protective covers. Nobody gets a medal for bleeding through a shirt during a 10K. Prevention wins.
The biggest practical lesson is that nipple fissures usually heal best when people stop treating them as a character test. You do not need to endure unnecessary pain to prove dedication to breastfeeding, fitness, or toughness. You need the right cause, the right fix, and the right support. When pain persists, professional help can turn a frustrating cycle into a manageable plan.
Conclusion
Nipple fissures are common, painful, and usually treatable. Whether caused by breastfeeding latch problems, pumping friction, athletic chafing, dry skin, eczema, infection, or irritation, the key is to identify what is damaging the skin and correct it. Soothing products may help, but they work best when combined with better latch, proper pump fit, breathable clothing, gentle hygiene, and timely medical care when symptoms suggest infection or another condition.
If a nipple crack is mild and improving, careful home care may be enough. If pain is severe, bleeding continues, redness spreads, fever appears, or the skin does not heal, contact a healthcare provider. Your body is not being dramatic. It is asking for help, and help is exactly what healing requires.
