Why Do My Nipples Hurt? 8 Common Causes of Nipple Pain Explained

Introduction

Nipple pain isn’t often talked about, but it’s a far more common issue than most people realize. Whether you’re a breastfeeding parent, a dedicated athlete, or simply navigating hormonal changes, nipple discomfort can strike at any stage of life. And let’s be honest—it’s uncomfortable, sometimes embarrassing, and occasionally downright painful.

So what causes nipple pain, and more importantly, what can you do about it?

For some, the discomfort is temporary and minor—just a bit of irritation after a workout or new laundry detergent. But for others, nipple pain is chronic, intense, or signals a deeper health issue. Understanding the potential causes is the first step toward relief and prevention.

In this detailed guide, we’ll dive into the 8 most common reasons behind nipple pain, explain how to recognize them, and walk you through how to treat or manage each situation. Whether you’re experiencing a mild sting or persistent burning, we’ve got you covered.

1. Friction and Mechanical Irritation

When Movement Meets Sensitive Skin

By far, one of the most frequent culprits behind nipple pain is good old-fashioned friction. Think about it—your nipples constantly come into contact with clothing, especially during physical activity. Athletes and active individuals are no strangers to the notorious “jogger’s nipple,” where repeated rubbing during running, cycling, or other movement-heavy sports leads to irritation, redness, and sometimes bleeding.

Signs and Symptoms

• A raw, chafed feeling during or after activity
• Redness or dry, cracked skin on or around the nipples
• Burning or stinging sensations with clothing contact
• In more severe cases, bleeding or open sores

Friction-related pain often worsens with tight or poorly fitting clothing. Ill-fitting bras, rough seams, synthetic materials, or sportswear that lacks moisture-wicking properties can all increase your risk.

How to Fix It

• Wear moisture-wicking, seamless sports bras or shirts
• Apply barrier creams or petroleum jelly before exercise
• Use nipple guards or adhesive bandages during high-impact workouts
• Opt for breathable fabrics like cotton when lounging

Pro tip: Always wash workout clothes thoroughly. Sweat build-up can harbor bacteria that might aggravate irritated skin.

2. Breastfeeding and Pumping Issues

Feeding Your Baby Shouldn’t Hurt—But Sometimes It Does

For nursing parents, nipple pain is one of the top complaints in the early stages of breastfeeding. And while some discomfort can be normal at first, ongoing or severe pain isn’t something to ignore.

The main offender? Incorrect latching. If your baby isn’t latching properly, their gums and tongue can compress the nipple in a painful way, often causing sharp or stabbing pain during and after feeds.

Other Common Triggers

• Improper use of breast pumps: Suction settings that are too high or shields that don’t fit well can bruise or crack the nipple.
• Teething infants: Babies might bite or latch differently, suddenly introducing pain into an otherwise smooth nursing experience.
• Vasospasm: A painful condition where the nipple turns white and throbs due to restricted blood flow after feeding.

What You Can Do

• Work with a lactation consultant to improve latching
• Ensure your breast pump settings are gentle and shields fit properly
• Apply warm compresses to soothe vasospasm or soreness
• Use nipple creams or ointments after feeds (lanolin or prescription-based)

Don’t wait too long to seek help—ongoing pain can lead to cracked nipples and open the door to infections like mastitis or thrush (more on that soon).

3. Skin Conditions and Allergic Reactions

Your Nipples Deserve Skincare, Too

Skin conditions like eczema or contact dermatitis don’t just affect hands or elbows—they can target the delicate skin of the nipple and areola, causing significant pain.

If your nipples are red, itchy, flaking, or appear blistered, you might be dealing with atopic dermatitis or a reaction to an irritant.

Common Irritants Include:

• Laundry detergent
• Fabric softeners
• Body lotions or scented soaps
• Bras made with synthetic materials
• Perfumes or deodorants applied too close to the area

How It Feels

• Burning, stinging, or itching
• Crusty or flaky skin
• Discoloration (red or darker patches)
• Raw skin that doesn’t improve with basic moisturizers

Smart Solutions

• Switch to hypoallergenic, fragrance-free products
• Avoid synthetic or textured fabrics on the nipple area
• Use a gentle, unscented moisturizer daily
• Apply medicated creams as prescribed (for eczema or dermatitis)

If symptoms persist or worsen, see a dermatologist. Skin reactions can become chronic if not addressed early.

4. Hormonal Changes and Menstrual Cycle Shifts

Blame It on the Hormones

For many people, nipple pain comes and goes like clockwork—with their menstrual cycle. That’s because rising levels of estrogen and progesterone cause the breast tissue to swell and retain more fluid, leading to tenderness that often extends to the nipples.

This premenstrual breast pain usually starts about a week before your period and eases once menstruation begins.

Pregnancy and Birth Control

• During early pregnancy, sore nipples and sensitive breasts are often the first signs. The areola might darken, and the nipples can feel hypersensitive to touch, clothing, or temperature.
• Hormonal contraceptives may also cause temporary breast or nipple tenderness, especially in the first few weeks after starting or switching birth control.

Coping Mechanisms

• Use over-the-counter pain relievers (like ibuprofen or acetaminophen)
• Wear supportive, comfortable bras without underwire
• Try warm or cold compresses to soothe sensitivity
• Track symptoms using a period tracker to identify patterns

If the pain is severe or affects your daily routine, a conversation with your doctor about hormonal management options might help.

5. Bacterial Infections: Mastitis and Beyond

When Inflammation Turns Into Infection

Mastitis is a painful bacterial infection that primarily affects breastfeeding women, but it can happen to anyone under certain conditions. It usually starts when bacteria enter through cracked or irritated nipples—often due to latching issues, friction, or poor hygiene. Once inside, the bacteria can multiply quickly, leading to swelling, heat, and intense pain in the breast.

Recognizing Mastitis

• Red, swollen, or warm breast tissue (usually in one area)
• Nipple pain or burning, especially during feeding
• Fever or flu-like symptoms
• Thick or pus-like discharge
• A hard, painful lump in the breast

In some cases, untreated mastitis can evolve into a breast abscess, which may require surgical drainage.

Risk Factors (Even if You’re Not Breastfeeding)

• Nipple piercings
• Weakened immune system
• Skin conditions that create openings for bacteria
• Poor nipple hygiene or improper wound care

Treatment Options

• Prompt antibiotics (prescribed by your doctor)
• Gentle massage and warm compresses
• Proper breastfeeding technique to avoid further damage
• Adequate rest and hydration

If your nipple pain is accompanied by fever or visible breast changes, don’t delay—mastitis needs quick medical attention to avoid complications.

6. Fungal Infections and Nipple Thrush

A Burning Pain That Lingers

While bacterial infections tend to cause visible inflammation and swelling, fungal infections like nipple thrush are sneakier and often more stubborn. Caused by the yeast Candida albicans, thrush leads to persistent burning, stinging, and shiny or flaky skin.

For breastfeeding parents, this condition can create a vicious cycle of reinfection—especially if the baby also has oral thrush.

How to Spot Nipple Thrush

• Bright pink, shiny, or flaky nipple/areola skin
• Burning or stabbing pain during and after breastfeeding
• Symptoms that persist despite addressing friction or latch issues
• Pain that seems to worsen after antibiotic use

Thrush pain is often described as “hot needles” or “shooting electricity,” unlike the dull ache of engorgement or the rawness of chafing.

Risk Factors

• Recent antibiotic treatment
• Diabetes or immune suppression
• Incomplete drying after breastfeeding or showering
• Tight, non-breathable bras

Treatment Options

• Prescription antifungal creams or oral medications
• Treating both mother and baby simultaneously (if breastfeeding)
• Sterilizing pacifiers, bottles, and breast pump parts regularly
• Letting nipples air dry and avoiding plastic-lined nursing pads

Persistent thrush can be frustrating—but it’s manageable with the right antifungal strategy.

7. Rare But Serious Medical Causes

Paget’s Disease of the Nipple

This rare form of breast cancer often masquerades as eczema or dermatitis on the nipple but shouldn’t be ignored. Paget’s disease affects the skin of the nipple and is often linked to underlying breast tumors.

What to Watch For

• Persistent scaling, flaking, or crusty skin on one nipple
• Yellowish or bloody discharge
• Nipple inversion or flattening
• Pain or itching that doesn’t respond to standard treatments

If you’ve tried creams and moisturizers without improvement, it’s time to consult a specialist. A biopsy can confirm the diagnosis, and treatment may include surgery, radiation, or other oncology care.

Inflammatory Breast Cancer

Unlike typical breast cancers, inflammatory breast cancer causes redness, swelling, and nipple changes that can be mistaken for an infection or rash. It progresses rapidly and needs immediate attention.

Symptoms May Include:

• Sudden swelling or heaviness in one breast
• Red, hot, or thickened skin (peau d’orange texture)
• Inverted or misshapen nipple
• Persistent nipple pain with no clear cause

Because this cancer often lacks a palpable lump, it’s harder to catch through routine self-exams—making awareness of symptoms all the more important.

8. When to See a Doctor About Nipple Pain

Don’t Suffer in Silence

It’s easy to brush off nipple pain as “just friction” or a side effect of exercise, but persistent discomfort isn’t normal. Here’s when to seek medical help:

• Pain lasts more than a few days without improving
• You notice discharge (especially yellow, green, or bloody)
• There’s visible swelling, heat, or lumpiness in breast tissue
• Fever, chills, or flu-like symptoms accompany the pain
• You’re breastfeeding and experiencing sharp, ongoing pain
• Skin changes like crusting, flaking, or persistent redness appear

Even if the pain seems mild, changes in nipple appearance or function are always worth discussing with your doctor.
