Pimple-like bumps can appear on or around the nipple area. These are often benign and similar to pimples elsewhere on the body.
Common Causes
Pimple-like bumps on the nipple or areola stem from several factors related to the skin’s natural structures. Blocked pores are a frequent cause, including sweat glands, hair follicles, or specialized sebaceous Montgomery glands. These glands secrete oil, and when clogged with dead skin cells and sebum, a pimple can form.
Hormonal fluctuations, particularly during puberty, menstruation, or pregnancy, can increase oil production, making pores more susceptible to blockages. Friction from clothing, especially tight-fitting garments or sports bras, can irritate the skin and lead to chafing, which may also result in pimple formation. Poor hygiene or irritation from certain products might further exacerbate the issue.
Identifying a Nipple Pimple
A typical nipple pimple often appears as a small, red, and tender bump, sometimes presenting with a whitehead or pus, similar to acne on other body parts. It is important to distinguish these from other common structures on the nipple and areola, such as Montgomery glands. These are normal, small, painless bumps on the areola that produce oil for lubrication and are normally present, becoming more noticeable due to hormonal changes, especially during pregnancy. Unlike pimples, Montgomery glands should not be squeezed.
Other conditions that might resemble a pimple include folliculitis, which is an inflammation of hair follicles that can cause red bumps or pustules. Ingrown hairs, common in areas with hair follicles like the areola, can also create pimple-like bumps when a hair grows back into the skin. Cysts, which are fluid-filled sacs, and milk blisters (or blebs) in breastfeeding individuals can also appear as bumps. Most simple pimples will resolve on their own within a few days to weeks.
Safe Management and Treatment
Managing a nipple pimple at home involves gentle care to encourage healing and prevent infection. Keeping the area clean with mild soap and warm water can help. Avoid squeezing or picking the pimple, as this can worsen inflammation, introduce bacteria, and lead to infection or scarring.
Applying warm compresses to the affected area for about 15 minutes several times a day can help reduce inflammation and promote drainage. Wearing loose, breathable clothing can minimize friction and irritation, allowing the skin to heal. If the pimple is due to general acne, products with salicylic acid or benzoyl peroxide may be used on the breast skin, but direct application to the nipple itself should be done cautiously.
When to Seek Medical Advice
Seek medical advice if a nipple bump exhibits concerning signs. These include persistent pain, increased redness, swelling, or warmth around the bump, which could indicate an infection. A bump that grows larger, doesn’t resolve within a few weeks, or recurs frequently also warrants medical evaluation.
Other red flags include any discharge from the nipple, especially if it is bloody or unusually colored. Changes in nipple shape, such as retraction or inversion, or alterations in skin texture like dimpling or puckering (resembling an orange peel), should also prompt a visit to a healthcare provider. A doctor can diagnose the cause and recommend treatment, ruling out more serious conditions.
