The Most Common Causes of Rashes on the Armpits and How to Treat Them

Share :


The underarm region is a frequently afflicted area of the body that commonly manifests rashes. The skin in the armpits is thinner, hairy, and folded, which makes it more prone to dampness and irritation that can cause rashes. Underarm rashes can manifest in various ways. Find out about various types of underarm rashes and how to treat them by reading the following article.

 

What causes underarm rashes and how do you treat them?

Rash of the armpit is a condition characterized by inflammation of the underarm area. Irritation of the armpits may manifest as dry, white, or bumpy scales, reddened skin, or red regions.

A purulent rash is another possible symptom of armpit rash. This rash under the arms may continue for a few days before it goes away as soon as the irritating factor that caused it fades away. Psoriasis is one example of a chronic medical condition that can cause a rash to persist for a prolonged period of time.

While over-the-counter (OTC) medications can alleviate some kinds of underarm rashes, a prescription from a doctor is required to treat rashes caused by other conditions.

The following can both cause and treat underarm rashes:

 

Scratches

The underarm is a part of the body that is sensitive to friction, which occurs when the skin comes into contact with clothes for an extended period of time. Common indications of abrasions in the underarm may consist of a reddened rash, a sensation of burning pain, or skin that feels hot to the touch. To take care of this issue, choose loose-fitting clothes that minimize friction in the underarm area.

 

Candidiasis

Candidiasis is a prevalent factor contributing to underarm rashes. This rash is the result of a fungal infection produced by the Candida albicans fungus. Common symptoms of a fungal infection include localized edema, pruritus, and an erythematous rash. For the treatment of candidiasis, it is recommended to maintain cleanliness in the underarm region to prevent excessive moisture and administer antifungal medication.

 

Atopic dermatitis

Atopic dermatitis, such as eczema, can develop when the strength of the skin barrier is damaged, making the skin more susceptible to irritants and allergens. The skin ultimately becomes irritated, cracked, and pruritic. Eczema can manifest again at any time; however, it does not present itself with a rash.

The use of home remedies for eczema, such as the application of moisturizer and the administration of medications like antihistamines and hydrocortisone, can be effective.

 

Contact dermatitis

Contact dermatitis is a condition that arises when the skin comes into contact with a substance that causes an allergic reaction or irritation, leading to an immunological response. This allergic reaction typically occurs within a few hours after the skin comes into contact with the allergen or irritant. To treat this kind of problem, it is recommended to prevent irritants from coming into contact with the skin and to use antihistamine-containing medication for allergy relief.

 

Seborrheic dermatitis

A form of eczema known as seborrheic dermatitis may develop anywhere an oil gland is located, even under the arm. Symptoms of seborrheic dermatitis include a scaly rash that is red, itchy, and burning. Medications containing hydrocortisone or antifungals, along with proper skincare practices and avoiding irritants, can be used to treat seborrheic dermatitis.

 

Ringworm

A reddish-colored, itchy rash is a typical sign of ringworm. This fungus can cause skin problems all throughout the body, including in the underarm. Ringworm treatment includes administering antifungal medicine, reducing fungal causes, and compressing the itching area.

 

Intertrigo

Intertrigo is a skin rash that affects folds of skin, such as the underarm. The rash is caused by wet environments, which facilitate the growth of fungi or bacteria. An infection of the intertrigo rash, which is characterized by pruritus, burning pain, or heat, can produce an unpleasant odor. The treatment for intertrigo consists of reducing wet areas and administering antibiotics and antifungals.

 

Shaving armpit hair

Using a razor to shave underarm hair can cause irritation (razor burn), which manifests as reddish dermatitis. To prevent this, apply a moisturizer, lotion, or oil that is formulated for your skin type.


There are numerous factors that can cause a rash under the arm. If you experience a rash in the armpit, you can either visit a doctor or make use of the consultation features that are available in the Ai Care application by downloading the Ai Care application from the App Store or Play Store.
