There are many causes of nipple pain, some as simple as an allergy to laundry detergent or a bra that does not fit right. Nipple pain is also common in menstruating, pregnant, or breast-feeding people.
There are more serious causes of nipple pain, such as infections and cancer, so seeing a doctor for a proper diagnosis and treatment is important.
As a symptom, nipple pain differs from person to person. Some may feel their nipples are sore and tender, while others feel sharp pain or pain accompanied by itching.
In this article, we look at some of the possible causes of nipple pain:
Friction is the most common reason for the nipples to be sore. Friction can occur if the nipples rub against a shirt or poorly-fitting bra, during sports activities, such as running, surfing, or basketball.
Friction on the nipple can often cause soreness and a stinging pain. The skin may also become dry or chapped.
Furthermore, longer periods of exercise mean extended periods of friction, too. People who are sensitive to friction may choose to take extra precautions, such as wearing surgical tape on their nipples during exercise.
Nipples that have already been injured by friction, an allergic reaction, or are cracked or bleeding have a higher risk of infection. Lactation and breast-feeding may also increase the risk of infection.
It is possible to get a yeast infection of the nipples, which is a fungal infection caused by Candida albicans. This can be the result of damage to the surrounding tissue, recent antibiotic use, or when a person has a history of fungal infections.
A yeast infection, also known as thrush, at the nipples is often felt as a burning, stinging pain that does not go away by reducing sources of friction. The nipples may be bright pink and the areola may be reddish or flaky.
Many breast-feeding women describe thrush as sharp, hot pain immediately after the feed. Signs of the infection may also appear on their baby.
Mastitis is possible during pregnancy if milk becomes trapped in one of the milk ducts. Bacteria can start to grow in the duct and spread. This type of infection can cause a swollen, red, sore breast and nipple.
Mastitis needs to be treated with antibiotics. If it is left untreated, an abscess can form. Anyone experiencing the following symptoms as well as nipple and breast pain should see a doctor:
- fever or chills
- breast feeling warm to the touch
- skin redness on the breast and nipple
- irregular breast swelling
3. Allergy or atopic dermatitis
Pain and irritation accompanied by flaky, crusty, or blistering skin may be a sign of an allergic reaction or atopic dermatitis (eczema).
There are a variety of household products that can irritate the nipples or trigger flare-ups of existing skin conditions, such as atopic dermatitis. These include:
- body lotion
- laundry detergent
- shaving cream
- fabric softener
Other signs of an allergic reaction include red or chapped skin around the nipple and areola, and persistent itchiness. In some cases, a rash may occur.
A topical anti-inflammatory cream can treat minor cases, but a person should speak to a doctor if the rash or redness increases, spreads, and does not respond to an over-the-counter treatment.
4. Sexual contact
Sexual activity can be another cause of nipple pain. Body friction or sexual activity that involves the nipples can cause soreness. This pain is usually temporary and is often treated by simply giving the nipples time to heal.
Using moisturizers or nipple guards may help keep friction to a minimum and prevent symptoms from getting worse.
5. Hormonal changes
The normal hormonal changes in a woman’s monthly cycle can also trigger nipple and breast soreness. These symptoms are usually felt in the days just before her period starts, when increases in estrogen and progesterone levels draw more liquid to the breasts and cause them to feel swollen.
The pain associated with hormonal changes usually subsides when the period begins. If this pain continues for more than a few days, a woman may want to speak to her doctor.
6. Cancer and Paget’s disease
Some nipple pain and other symptoms can be a sign of issues such as cancer, although tumors do not usually cause pain. Nipple pain caused by cancer will often only affect one breast and nipple.
Paget’s disease is a rare type of cancer involving the nipple that commonly occurs alongside tumors in the same breast. People with Paget’s disease and breast cancer may experience other symptoms, including:
- a flattened or inverted nipple
- yellowish or bloody discharge from the nipple
- itching or tingling sensations
- reddish, flaky, crusty, or scaly skin around the nipple and areola
Paget’s disease and breast cancer are diagnosed by inspecting the affected cells. While Paget’s disease is rare, anyone who is uncertain about their symptoms should see a doctor.
7. Nipple pain during pregnancy
Nipple pain is also common during pregnancy or breastfeeding. The breasts may become larger and feel sore. The nipples and areola may darken and ache, and small bumps may pop up around the nipples.
Well-fitting support bras may help reduce friction and ease soreness. Some pregnant women find it helpful to wear a supportive sleep bra overnight, such as the one shown here. Sleep bras are also helpful for reducing nipple and breast pain after the baby is born.
Cooling gel packs, such as these, can also soothe inflamed or painful nipples caused by breast-feeding.
Breast-feeding is a common cause of nipple soreness. This is mostly due to the latching technique of the baby. If the baby does not have enough of the breast in its mouth, the nipple will be up against the gum and hard palate. Babies should latch deep on the breast with the nipple at the back of the throat.
If a mother uses a breast pump, this can also cause nipple pain. The pain may be caused by too much suction or using a nipple shield that does not fit correctly. Adjusting the breast pump to a more comfortable setting and acquiring properly-fitting nipple shields may help reduce discomfort.
An infant starting to teeth is another potential cause of nipple pain, as they may change how they latch on and even bite the nipple. A breast-feeding woman can try to encourage the infant to take more of the breast into their mouth, so they do not bite down as easily.
If a baby presses the nipple too hard between their gums and the roof of their mouth, it can restrict blood flow to the nipple. This can result in what is called a vasospasm, which is painful and causes the nipple to turn white, then red, then purple in quick succession.
Nipple pain caused by friction may be prevented by wearing a properly-fitted sports bra, smooth synthetic fabrics, or by using protective products, such as rash guards and nipple shields. Some creams or ointments may also help reduce friction.
Breast-feeding mothers are encouraged to seek the assessment and care of a lactation consultant to help their baby establish good feeding habits. Many health insurance plans cover this health need.

Nipple soreness caused by hormonal changes in menstruation or pregnancy may respond well to warmth or pain relievers, such as ibuprofen (Advil) or acetaminophen (Tylenol).
Breast cancer is frequently treated with surgery, radiation, and chemotherapy. Treatment of minor cases of Paget’s disease usually involves removing the nipple and using radiation therapy on the affected breast. Some cases may require the entire breast tissue to be removed.
In most cases, pain in the nipples is simple and will clear up once the cause is treated. Anyone experiencing persistent symptoms should see their doctor to discuss diagnosis and the correct treatment.
