Armpit rash causes, symptoms, and home remedies

An armpit rash is a change in the skin under the arm that impacts the color and texture of the underarm. When you have an underarm rash, it can be uncomfortable, unsightly, and embarrassing, but in many cases, home remedies can provide relief.

People of all ages can experience an underarm rash. The symptoms of the rash can vary depending on the person and the cause. Some people have armpit rashes that come and go quickly, while others have rashes in the underarm area that just won’t go away.

A rash is a condition that causes the affected skin to turn red, blotchy, and to swell in some cases. While rashes vary in location, pattern, and extent, an armpit rash can be an indication that something is irritating that specific area or it could be a sign of a body-wide condition.

Many armpit rashes can be itchy and difficult to ignore or hide, so it’s important to figure out what is causing the problem and how to address it.

Symptoms of Underarm Rash

In most cases, red blotches appear to indicate that you have a rash. In some situations, small red bumps or white bumps will also appear on the skin along with red patches.

Some of the other common symptoms of armpit rash are:

• Itchiness
• Bruising
• Pus
• Warmth or swelling
• Tenderness or pain

Other symptoms may occur along with the rash that could be related to a bigger issue that is happening within the body. A cough, fever and chills, headache, joint stiffness, and sore throat are signs that something more than just a rash may be involved.

A person should seek immediate medical attention if they have a rash and have a change in consciousness, have difficulty breathing, feel tightness or constriction in the throat, experience sudden swelling of the face, lips, or tongue, or if they observe worsening of symptoms despite treating the rash.

Types of Armpit Rash

There are a few different types of armpit rashes and uncovering the type you have can help you receive the best treatment.

Eczema is a common condition that produces an itchy, crusty rash. It is commonly found in the body folds like armpits. Since the rash is very itchy and people can’t resist scratching, bleeding can occur.

Another skin irritation called seborrheic dermatitis, which creates oily patches of flakes and is also itchy, can show up on the armpits. A good example of this is cradle cap in infants – it is a form of seborrheic dermatitis.

Candida is a yeast infection and commonly occurs in moist areas, like the armpit. It can cause swelling, itching, scaling, and red rashes. Candida can worsen in hotter weather, wearing tight clothing, or due to poor hygiene.

Lastly, there is contact dermatitis. This is a common rash that happens when a person comes in contact with an allergen or irritant.
