Raw-feeling nipples are almost always caused by friction, hormonal shifts, or skin irritation, and the sensation can range from mild tenderness to stinging, cracked skin. The cause usually becomes clear once you consider what’s changed recently: a new bra, a longer workout, a shift in your menstrual cycle, or a new soap or detergent.
Friction From Clothing or Exercise
The most straightforward cause of raw nipples is mechanical friction. Every time fabric slides across the nipple, it creates micro-irritation. Over a short errand, that’s nothing. Over a 10-mile run with thousands of strides, each one slightly shifting your shirt across your chest, it’s enough to crack the skin. This is sometimes called “jogger’s nipple,” and it affects runners, cyclists, surfers, and anyone doing repetitive upper-body movement in a shirt.
Several things make friction worse. Cotton shirts absorb sweat, get heavy, and cling to the chest, turning a soft fabric into a damp abrasive. Stiff shirt logos or seams that sit right over the nipple compound the problem. Cold weather makes nipples more erect and more exposed to rubbing. If your nipples feel raw after exercise or at the end of a long day in a rough bra, friction is the likely culprit.
Switching to moisture-wicking synthetic fabrics helps significantly. For running or cycling, adhesive nipple covers or medical tape create a barrier that eliminates the problem entirely. A well-fitted sports bra that compresses the chest and minimizes movement is another reliable fix. Anti-chafing balm applied before a workout works the same way lubricant prevents blisters on your feet.
Hormonal Changes
Fluctuating estrogen and progesterone levels directly affect breast and nipple tissue, making them swell slightly and become more sensitive. This is one of the most common causes of nipple rawness that seems to appear without any obvious external trigger.
Nipples are most likely to feel sore in the week leading up to your period, when progesterone peaks. Ovulation (mid-cycle) can also trigger sensitivity. Beyond the monthly cycle, hormonal shifts during puberty, pregnancy, perimenopause, and while taking hormonal birth control all produce the same effect. During early pregnancy, breast changes often begin between weeks four and six, though some people notice sensitivity as early as two weeks after conception. If your nipples feel raw on a predictable monthly schedule, hormones are almost certainly responsible.
Skin Irritation and Eczema
Nipple skin is thinner and more sensitive than surrounding breast skin, which makes it especially reactive to chemicals in everyday products. Harsh laundry detergents, scented soaps, lotions with artificial fragrances or dyes, and perfumes can all trigger contact dermatitis, leaving the nipples red, flaky, and raw.
Nipple eczema is a specific and surprisingly common form of this. It shows up as itchy, scaly patches that are often on both sides and can extend beyond the areola onto surrounding skin. Flare-ups worsen with exposure to irritants or scratchy fabrics like wool and polyester. If this sounds familiar, switching to unscented laundry detergent designed for sensitive skin, wearing cotton bras and shirts, and avoiding fragranced body products can make a noticeable difference. If the irritation persists, a doctor can confirm eczema and recommend a topical treatment.
Breastfeeding and Latch Issues
For anyone currently nursing, a shallow latch is the number one reason nipples feel raw. When a baby attaches only to the nipple rather than taking a deep mouthful of the areola, the suction concentrates on a small area of delicate skin, quickly causing pain, cracks, and bleeding. Signs of a shallow latch include seeing most of your areola while the baby feeds, the baby’s mouth being only slightly open, their chin not resting against your breast, and pain that doesn’t ease after the first few seconds of a feeding.
A lactation consultant can help correct positioning, which often resolves the soreness within days. In the meantime, lanolin cream applied after feeds helps heal cracked skin (skip it if you have a wool or sheep allergy). Silver nipple cups placed over the nipple between feedings promote healing for cracks and abrasions. Hydrogel pads offer cooling relief. If you’ve been using a cream or balm for more than a week with no improvement, stop and try a different approach, because some nipple pain during breastfeeding is caused by a yeast infection rather than mechanical damage.
Yeast Infections on the Nipple
A fungal infection on the nipple typically causes a burning or shooting pain that persists between feedings (not just during them), along with redness, swelling, cracked skin, and itching. It’s most common in breastfeeding women but can happen to anyone. The warm, sometimes moist environment around the nipple creates favorable conditions for fungal overgrowth, especially after a course of antibiotics or if the skin is already damaged from friction or eczema. This type of infection requires a prescription antifungal, so over-the-counter moisturizers alone won’t resolve it.
When Rawness Signals Something Else
In rare cases, a persistent raw or scaly patch on the nipple can be a sign of Paget disease of the breast, a form of cancer that starts on the nipple itself. It looks like a pink or red, scaly patch that begins on the nipple and gradually spreads outward to the areola. It can easily be mistaken for eczema, and it sometimes temporarily improves with steroid creams, which delays diagnosis.
A few features help distinguish it from ordinary eczema. Paget disease always involves the nipple and is typically on one side only. Eczema, by contrast, usually affects both nipples and often extends well beyond the areola onto surrounding skin. If you have a scaly, crusted nipple rash on one side that doesn’t fully heal after a few weeks of treatment, a biopsy is the definitive way to rule out Paget disease.
Nipple discharge is another signal worth paying attention to. Clear or bloody discharge that comes from a single duct in one breast, especially if it happens on its own without squeezing, warrants prompt evaluation. This is particularly important for anyone who is past menopause.
