In this article, we’ll look at rashes under the breast, including yeast infection, fungal and bacterial infections and heat rash. They cause itching and discomfort, and we’ll show you what they look like and what to do about them.
Rashes under the Breast
At times, the skin under your breast may become irritated and red. It’s called breast itch, and sometimes Intertrigo. This rash can be itchy, but may also be painful, and may be accompanied by blisters.
If you work in hot, humid conditions, you may develop a rash beneath your breast. If you are pregnant or overweight, your chances are greater to develop this issue. For you to treat it properly, you need to know its underlying cause first.
The main causes of rashes under the breast include heat, excessive sweat and lack of air circulation. If your bras don’t fit properly, they can also rub against the breasts and the skin beneath them, bringing on a rash.
In some instances, the rash may lead to a fungal infection. Fungi and yeast thrive in moist, warm environments, and the area beneath the breasts is a perfect place for them to grow. In addition, allergic reactions or breast infections can cause burning sensations, itchiness, red patches and general discomfort.
Heat Rash under the Breast
Many women may develop Intertrigo and various other types of rashes under their breasts, during the warm summer months. They are also more common in women with larger breasts, and during the months of pregnancy.
Malodorous heat rash on your chest or underneath your breast may develop from changes in hormones that cause excessive sweating. In addition, your breasts will usually swell during pregnancy, and the resulting folds of skin may rub and cause rashes.
Prickly Heat Rash
As is the case of prickly heat rash elsewhere on the body, prickly heat breast rash typically has these symptoms:
- Painful and itchy rash
- Red pimples or pustules in skin folds under your breasts
- Bleeding or soreness with rash
- Foul smell coming from rash
If you wear any type of tight clothing, this can lead to more chafing and may add to the irritation. If you don’t treat the rash, it may develop into bacterial or secondary infections of the skin.
Some heat rash cases under breasts become so painful that patients will consider surgeries to reduce the size of their breasts, to prevent this problem, which is often chronic.
Prickly heat rash is not serious under most circumstances, but it may cause a lot of pain and irritation. Here are some of the most often used home remedies for the treatment and prevention of chronic heat rashes found under the breasts:
- Don’t wear a bra if you don’t have to. This is especially important if you typically wear underwire bras. These will worsen inflammation and increase the amount of chafing. If you must wear a bra, choose some that are 100% cotton, and avoid nylon bras, which may make your irritation worse.
- Make an effort to remain as cool as you can. Stay out of the sun, especially between 10 AM and 3 PM, which are the hours when the sun is strongest. Seek out shade whenever you can.
- Treat your heat rash with gel from the aloe Vera plant or powders that soothe prickly heat. These will help in the prevention of redness, pain and itchiness that are caused by rashes under the breast.
- Baking soda can help to alleviate breast rash pain and itching, too. Mix baking soda with water to make a paste. Then apply it directly to the itchy, red skin, to relieve inflammation, itchiness and pain.
- Make sure that your rash was not started by fungus. A fungal rash beneath the breasts is common if you suffer from diabetes. Have your physician check your blood sugar levels, especially if you know you have gestational diabetes.
Bacterial Rash under the Breast
Some heat rash cases are brought on by bacterial infections. These can be spotted because of their formation of pus. Have this irritation treated by seeing your physician for a prescribed topical or oral antibiotic.
During the summer months, bathe or shower in cool water, as much as you can. You may enjoy a soak in a warm tub with colloidal oatmeal, too. It will soothe and cool your skin. If your hair dryer has a “cool” setting, you can blow it on the areas under your breast for relief.
Make sure to fully dry the skin after you bathe. Don’t use body wash, cosmetics or soap in the area beneath your breasts, to avoid irritation.
Fungi and bacteria are found everywhere, including the skin under the breasts. If there, they could cause itching and irritation. Bacteria love warm and moist areas, so this area is more prone to skin rashes than most other parts of your body.
Bacterial and fungal infections are commonly culprits of under-breast rashes, but chronic skin disorders and skin allergies may lead to rashes that itch under your breasts. Keeping your skin dry and clean, watching out for possible triggers and visiting your dermatologist when you need to, are important, in order to prevent recurring rashes.
Extended antibiotic use, uncontrolled diabetes, obesity, HIV and chronic use of steroids are high risk factors for skin infections from Candida yeast. These rashes will usually clear up relatively quickly with the application of anti-fungal creams.
Keep the area under your breasts dry by sprinkling anti-fungal powder on it. Nystatin is a popular choice. If you get rained on or sweaty, remove the wet clothes and bra as soon as you can and then shower, before drying your skin well.
Oral antibiotics like Augmentin are the only medical topical treatment for bacterial infection rashes.
Rashes caused by Allergies
If you have skin allergies, this can also cause a rash under your breast. If your rash was caused by allergies, it’s known as allergic dermatitis. This is usually very itchy and red. If you have a history of inflamed, flaky skin elsewhere on your body, or asthma, in addition to seasonal allergies, you have a higher risk of contracting allergic dermatitis.
Allergic triggers may vary from one person to the next, but some of the most common irritants include lotions, perfumes and laundry detergents. Allergic rashes are usually treated with hydrocortisone or other topical steroids. You shouldn’t use topical steroids in the long term, since it can cause overgrowth of fungi and chronic changes in your skin.
Psoriasis is another common skin disorder, leading to scaly, red, itchy skin patches. It generally affects the knees and elbows most. An offshoot known as inverse psoriasis can develop in the folds of skin under your arms or in the groin area, in addition to the skin beneath your breasts.
Yeast Infections under the Breast
Fungal infections in the skin that overlies the breast are commonly called breast fungus. This doesn’t mean that the deeper tissues of the breast are infected. These fungal infections of the skin are common, and more often found on the groin and feet, but they can affect skin anywhere on your body.
Rash under Breast – Getting rid of it
Rashes under breasts are common issues. You can use natural DIY remedies to relieve the symptoms. If you see any signs that might indicate an infection, consult your physician.
- Cold compresses
Cold compresses can help to alleviate many symptoms, including the burning sensation and itching that are caused by a rash under the breast.
Wrap ice in a clean wash cloth or hand towel and place it against the rash for five or 10 minutes. Repeat this process after a short break.
You can also use skim milk along with cold water and dip the wash cloth in it. This can reduce swelling and relieve the itching.
If you can tolerate it, bathe in cold water. This helps to close your pores, which reduces sweating and thus the rash.
- Tea tree oil
This oil is an anti-fungal, so it works well in treating a rash under your breast. It also prevents fungal growth and infection.
This remedy should be used after a shower and again before you go to bed.
- Mix six drops of essential tea tree oil with four tablespoons of organic extra virgin olive oil.
- With a cotton ball, dip into mixture and then dab it on your rash.
- Massage the affected area very gently, to help the oil to penetrate the skin.
You should notice some clearing of the rash within several days.
Sometimes, chemical residue left on your clothes by detergent may lead to a breast rash. If this is the cause of your rash, vinegar could be helpful in remedying it.
- Mix a half cup of white vinegar in a half-bucket of water. Wash all of your bras in this solution and allow them to hang outside to dry.
- You can also apply apple cider vinegar to the skin that is irritated. Wash it first with warm water and a mild soap. Then rinse the skin with cold water and pat it dry.
- Direct help may be obtained by mixing a teaspoon of vinegar in one cup of warm water and applying it to the area affected. Do this dabbing two or more times a day. Don’t use it if it causes any discomfort.
Dealing with a breast rash can be done directly by reducing how much sweat accumulates there.
- Place a thin square of cotton between the skin beneath your breasts and the lowest part of your breasts. This creates a barrier and absorbs moisture. Soft dinner napkins can be used if you prefer.
- Wear clothing that is lightweight and preferably cotton. This absorbs more moisture and will keep your body from becoming as sweaty. This will reduce the chances of a rash under the breast.
