RASHES IN ARM PITS
A rash occurs when an area of skin, such as the armpit, looks unusual or feels uncomfortable for more than a few hours.
In most cases, a rash is a temporary symptom that is usually treatable with over-the-counter (OTC) medications and home remedies.
However, some rashes, such as long-lasting, returning, or severe rashes, may be a sign of underlying health conditions that require medical attention and treatment.
In this article, we examine different types of armpit rash and explain the treatment options for each one.
Causes
There are many different causes of armpit rash. The most common ones are listed below:
Chafing
Armpit rash
Chafing, heat rash, and eczema may cause armpit rashes.
When skin rubs hard against itself or clothing for too long, irritation is likely to occur. Areas of the body where the skin folds over itself or rubs against itself frequently, such as the armpit, are especially prone to chafing.
Chafing rashes are usually:
red
raw, or with the top layer of skin rubbed off
stinging and burning
in streak formations, often with a lighter center streak
swollen, cracked, and bleeding or crusted if severe
Many people experience underarm chafing while exercising or wearing clothing that does not fit them properly.
Many people also experience chafing during the spring and summer months because they sweat more in the heat and moist skin is quicker to irritate.
Heat rash
Heat can mix with sweat on the skin and cause an irritation rash commonly called heat rash.
In most cases, heat rash causes itchy patches of bumps that are:
tiny
prickly
red
slightly raised
Many people develop heat rash in their armpits during the warmer months or while in hot climates because the armpits contain lots of sweat glands.
Contact dermatitis
Contact dermatitis occurs when the skin or body comes into contact with an allergen or irritant, sparking an immune response. This allergic reaction usually develops within a few hours of exposure to allergens or irritants.
Contact dermatitis rashes are usually:
itchy
red
blistered
dry
There are many different causes of contact dermatitis. Some of the most common include:
chemicals found in cleaning detergents and personal care products
food or environmental allergens
medicines
insect stings or bites
Hair removal processes
Many people develop patches of tiny, red, painful bumps after shaving the underarms. These bumps are usually present in and around the hair follicles.
