Effective rash on armpit treatment requires a proper diagnosis to determine the reason for its appearance.
In this part, we are going to focus on causes. However, while looking at the various causes, we will give you some ways to treat, heal or cure them. This treatment will be specific to the purpose. Later on, we will mention a few general cures that will include home remedies and cream. So, what causes them?
Armpit hair shaving using a razor, especially an old or dull blade can irritate, break, cause razor burn, raised red bumps, ingrown hair or even cause infections to the delicate and sensitive leading to an armpit shaving rash.
Some people will also have rashes after epilating or plucking hairs. For armpit hair removal, try waxing, laser hair removal, use shaving creams and make slow and short strokes to minimize skin damage.
Another common cause is sweat rash which is primarily caused by blocked sweat ducts that “trap perspiration under your skin. Symptoms range from superficial blisters to deep, red lumps” [Mayoclinic.org].
It commonly affects babies but can affect adults (men and women) too. See the below heat rash picture to get a hint on what you expect.
Besides blocked ducts, as heat increases, moisture, friction, and chafing in the underarm usually increase too, leading to discomfort and rashes. They are “often pimply in appearance, or may have small raised bumps” [skincare.lovetoknow.com] and are common when temperatures are high especially during summer.
You do not need any heat or sweat rash treatment since it clears on its own. To help reduce the effect of heat on your armpits as well as heat rash under armpits symptoms, try to wear loose and cool clothing during hot seasons and use calamine lotion or hydrocortisone cream to soothe it.
Having candida (yeast infection) on your underarm can lead to a rash. Commonly, they affect, “almost any area of the body, but are more commonly in intertriginous regions—where two skin areas may touch or rub together—such as armpits, the groin, skin folds, and the area between the fingers and toes” [Healthline.com].
Candida albicans thrives well in warm and moist environments, something your underarms will provide, especially if you have sweaty armpits. Furthermore, hot weather, poor hygiene and wearing tight-fitting or restrictive clothing allow candida infection to multiply and spread.
People who are overweight, have diabetes, have undergone antibiotic therapy, have weak immunity, e.g., suffering from HIV aids STD, work in wet conditions, have inflammatory disorders or pregnant, i.e., during pregnancy mothers have an increased risk of suffering from candida including an underarm fungal infection.
When you have a candida fungus infection, you will have itchy rashes, red-purple patches (i.e., red circular rings), yellow or white substances on the affected area, scaling (or flakes), cracked skin, soreness, redness, pus-filled pimples on margins of regions affected, among other symptoms.
Treatment is by use of antifungal (OTC drugs such as ketoconazole, clotrimazole,) amphotericin B., nystatin, or anti-fungal lotions, ointments and creams.
Hidradenitis suppurativa or acne inversa refers to “a painful skin disease-causing abscesses and scarring of the skin” [webmd.com] that often affects the anus, buttock, groin, breast and armpit areas but can spread to the neck, back, legs or face. The cause is not apparent, but it is assumed to be inflamed hair follicles or blocked apocrine sweat glands.
This condition can be cured but corticosteroids, retinoid (vitamin A) based medications, adalimumab, biologics infliximab, ciclosporin, laser or surgical treatments among other treatments.
In its initial or early stages, HIV manifests itself with rashes which can affect various parts of your body, including armpits, chest, shoulders, and so on.
This usually occurs within two months of infection where you will have “flat or barely raised rashes with small reddish dots/ spots (i.e., spotty rash under armpit resembling eczema) in people with light skin, and dark purple/ black in people with dark skin” [dred.com].
Typically, the one caused by HIV is not itchy and will disappear within three weeks. However, If it is itchy, try hydrocortisone cream or Benadryl to reduce itching, avoid hot showers, direct sunlight or hot baths.
If you are a fan of deodorants and you suffer from this problem quite often, it could be from the deodorant or antiperspirant you are using. This happens if you are allergic to some of the ingredients present. Armpit rashes due to deodorants are often “itchy, bumpy, and red and can blister, peel, flake and ooze” [allergies.about.com].

Staph is a methicillin-resistant Staphylococcus aureus (MRSA) resistant to beta-lactam antibiotic. There are two types, the CA-MRSA, associated poor hygiene, contact and touching contaminated things while the HA-MRSA related to surgical procedures, intravenous catheters, and so on.
The CA-MRSA often affects scratched, cut or rubbed areas as well as areas with more body hair “buttocks, armpits, back of the neck, and beard…yellow or white center and a central head” [Healthline.com]. The infected areas become swollen (fluid-filled), red and painful if you touch them.
