Armpit rash

An armpit rash can last for a few hours up to months. Generally, the rash can be red, scaly, bumpy or white. The rash might not be evident right away, but the irritation and itchiness can be unbearable in some cases.

There are various causes of an armpit rash. Determining the root case will make it easier to provide relief. If the rash is due to warm weather, it settles on its own. If caused by certain skin conditions, it might last longer and require specific care.

What are the types of armpit rash?

  • Atopic dermatitis or eczema – this rash generally starts in childhood and can form on the body folds including the armpits. It is typically itchy, reddened and can crust over.
  • Contact dermatitis – this type of armpit rash might arise if exposed to an irritant or allergen. The fragrance in lotion or deodorant can trigger the rash. Using a new laundry detergent or even the type of fabric can cause the rash.
  • Seborrheic dermatitis – this is a form of skin irritation partly due to the excess production of sebum.
  • Candida – this is a form of fungus or yeast infection. It generally affects moist parts of the body including the underarms.

Management

If the armpit rash is caused by contact dermatitis, it is vital to pinpoint the irritant and avoid exposure.

Aside from the removal of the irritants, an armpit rash can be soothed by the following:

  • Take a warm bath with colloidal oatmeal
  • Apply a cold compress on the site
  • Over-the-counter anti-itch creams
  • Apply an unscented moisturizer for dry skin and eczema

It is also vital to avoid scratching the irritated area. Remember that scratching will only make the skin prone to infections.

In some cases, stress can worsen some forms of dermatitis. Relaxation techniques can also deal with the rash.
