Usually, a rash under your breast (or in the folds of your skin) is caused by a condition known as intertrigo. It is a typical condition that can occur at any point in your life. 


Such a rash looks like thickened skin that is red, swollen, and scaly in appearance. It can also be itchy and sore, and in some cases, it may also have a nasty smell.


Aside from all this, it can either be an infection, an allergy, or a severe medical problem that would require proper attention.


What To Know About Rash Under Your Breasts?


In order to tackle such rashes, it is essential to know what the prominent signs are. Signs of a rash are discolouration of the affected area, inflammation, and redness. 


The main reason such rashes make their horrifying appearance is the friction present between the rubbings of skin. Other causes include moist areas such as the thighs, under the knees and the arms.


For bacteria and yeast, areas with moisture are the perfect conditions to live. Hence, you must take the steps mentioned in this article and avoid getting rashes that itch or bleed.


More factors that trigger rashes are heat, tight clothes and lack of air circulating in the affected areas. Women, who wear the wrong size bra, don’t keep the area dry or live in quite humid areas are most likely to experience this sort of pain.


Did you know that more than half of women around the world wear the wrong size bra? A 2012 study conducted in the United Kingdom claimed that 80% of women wear the wrong size bra.


Such rashes are both simple and mild in most cases, but they can quickly escalate to a severe issue that may require the attention of a medical professional. To avoid hitting that point, you must know about the various types of rashes and their causes.


Now that we know what a rash under the breasts looks like and how it occurs – let’s discover its types and causes.   


Types Of Rashes


Rashes can range from different skin conditions, infections, and autoimmune disorders. Therefore, it is crucial to know when to tend to these rashes at home and when you should see a doctor.


As these rashes are pretty different from one another, they have their own sets of symptoms, signs, types and causes.


Infections


As mentioned before, a warm and moist area is the perfect breeding ground for bacteria and yeasts. And because wearing clothing that fits too tightly doesn’t allow a lot of air to pass through, it can result in the following types of infections:


  1. Candidiasis

Candidiasis caused by yeast (which is a type of fungus) is a fungal infection called Candida. Candida yeasts are most likely to form under your breasts as well.


Usually, it appears as a glossy red rash in the damp folds of your breasts. However, if the yeast continues to grow, it is apparent that it might burn, itch and even bleed. For recovery, antifungal medications are recommended. 


If the case is severe and widespread, your doctor may recommend taking medications. Apart from that, it is essential to keep the infected area dry and clean at all times.


  1. Cellulitis

Cellulitis is known as a bacterial skin infection that causes swelling, tenderness, blisters and inflammation in the area where it attacks.   


The responsible bacterias (streptococcus and staphylococcus) enter the skin through a crack, wound or bug bites. If not treated immediately, it can become life-threatening. Like all other rashes, skin affected with cellulitis can be sore and bleed if rubbed too much.


Treatment for cellulitis usually involves antibiotics taken by mouth, and your doctor shall prescribe the range of time. Your doctor can also recommend pain killers if your rashes are beyond bearable.


Skin Conditions


Certain common skin conditions can aid in the appearance of a rash under your breasts. These conditions can result from allergies caused by specific food items, reactions to any medications you might be taking, or any insect bites.


  1. Hives

Hives are either red or skin-coloured swollen bumps that are tender upon touching. They can cause severe itching and might redden. They are usually triggered due to a food you are allergic to and don’t know yet.

In a standard case, your doctor will recommend antihistamines that don’t make you drowsy. If they don’t help, you might have to see an allergist.


  1. Psoriasis

Psoriasis is a result of a fragile immune system that causes diseases to attack you. They are known to be red, scaly, and itchy patches that have silvery scales. Psoriasis is a chronic disease with no cure.


In order to stop the disease from escalating, your doctor may recommend corticosteroids- which are drugs that are mostly prescribed to treat mild to moderate psoriasis. Other treatments are given according to the level and degree of psoriasis that has attacked the skin.


  1. Scabies

Scabies can be caused by the bite of the human itch mite. This insect thrives on the upper layer of skin and lays its eggs. The marks appear red and almost pimple-like, and you’ll soon develop an itchy rash.


This disease or rash can spread from person to person and move quickly. As for the treatment, your doctor may recommend ointments or even oral medications. Adding on, you must be prepared for the state where the recommended treatment doesn’t ease your rashes.


Being prepared and vigilant beforehand will be beneficial as you’ll be able to discuss the early signs with your doctor.


Autoimmune Disorders


Autoimmune disorders are chronic diseases as well. They cannot be treated but only controlled. You can have your symptoms cured, but it won’t finish entirely.


Eczema


Eczema is a skin condition that makes your skin bumpy, red, dry, itchy and tender. Over time, your skin can become prone to irritation and constant itching. This disease can strike you even at the tender age of 5.


If you happen to contract eczema, your doctor may recommend you keep your skin moisturised. They shall also tell you not to use strong scented perfumes or body items since that can aggravate your condition.


More complex treatments can also be put into action if the basic ones don’t seem to help your condition within a few months.


Other autoimmune diseases also include:


  • Inverse psoriasis
  • Hailey-Hailey disease
  • Hyperhidrosis

Conclusion


Remember that all the mentioned diseases and conditions require undivided attention. If you don’t tend to these rashes that can appear under your breasts, then you might face a severe problem.


Prevention is better than cure. However, in this case, even if you happen to witness such rashes on your skin, then it would be better if you talked about it to your doctor.
