What are itchy armpits?

An itchy armpit refers to the sensation where the underarms are experiencing irritation or discomfort which can trigger the urge to scratch or rub the affected region.
Itchy armpits can be caused by a variety of reasons such as poor hygiene, excessive heat or dry skin patches. Itchiness in the underarms can be a very uncomfortable feeling, so read on to learn more about how to get rid of and prevent them.

What are the symptoms of itchy armpits?

Itchiness or irritation in the underarm, ranging from mild to severe.

Red patches under the armpits.

Swelling, bumps, or armpit pimples.

Rashes in the underarm area.

Itchy armpit without redness, where the skin feels irritated but shows no visible signs (often due to dry skin or sensitivity to products).

In some cases, you may experience an itchy armpit without redness, where the skin feels irritated but shows no visible signs. This could be due to dry skin or sensitivity to products used under the arms.

Seek medical help if the itchiness persists or is accompanied by severe pain or other general symptoms, as it could indicate an infection or other illnesses, sometimes serious.

Causes of itchy armpits

9 Reasons why your armpits are itchy

Itchy armpits can be caused by a variety of factors such as:

1. Heat

When exposed to too much heat, your sweat glands clog up and cannot release sweat. This causes them to swell, resulting in itchy, painful bumps under your arms.

2. Unsuitable hygiene

Keeping your underarms clean is vital to preventing itchy armpits. Underarms harbour many different kinds of bacteria. The buildup of sweat and dirt on the skin can promote these bacteria to multiply which could cause itchy skin. It is important to use a suitable gentle cleanser to remove dirt without irritating the skin.

3. Razor burns or rashes

This typically occurs when an area is not shaved correctly which can lead to irritation or itchiness. If you develop a razor burn or rash, take a break from shaving for a few days and allow your skin to heal.

4. Contact dermatitis

This occurs when the skin is exposed to an irritant or an allergen, leading to redness and irritation. Such substances can include soaps, laundry detergents, or certain deodorants. These types of reactions under the arms are common and can be triggered by ingredients like alcohol, fragrances, or certain preservatives found in personal care products. A skin rash caused by deodorant may appear as redness or a burning sensation under the armpits after applying deodorant. This may be an allergic or irritant reaction. Wash the area thoroughly to remove any residual deodorant and prevent the situation from worsening. Consult a specialist to find out which ingredients to avoid in the event of an allergy.

5. Intertrigo

This is a rash that occurs in moist areas of skin folds. It is characterised as a red or brown rash that can cause itchiness and burning sensations. It is often infectious in origin, but can also be linked to other conditions such as eczema or psoriasis.

6. Ingrown hairs

This occurs when a hair follicle grows sideways under the skin. This can lead to the formation of boils or pimples under the armpits, which are often red and painful to the touch.

7. Sensitive skin

People with sensitive skin may be more prone to itchy armpits. The use of some deodorants can cause irritation, especially to those with sensitive skin. Use gentle, alcohol-free products with a fragrance designed for sensitive skin to help prevent itchiness.

8. Lymph node infection

Underarm pain accompanied by a small lump may indicate an inflamed lymph node. This is often a sign of a fungal or bacterial infection, which is why you should consult a doctor.

9. Some cancers

Such as lymphoma or rare breast cancers, can cause itching. If you experience any other symptoms or have any doubts, always check with your doctor.

If you’re experiencing extreme symptoms, it's advised you seek medical attention.

Why do my armpits itch at night?

A burning or itchy sensation which occurs in your armpits at night could be because of several reasons. Most itchy conditions can be made worse at night by heat and excessive sweating. If this is the case for you, make sure your bedroom is well ventilated and use light bed linen and clothing that allows the skin to breathe. If you experience itching, pain or excessive sweating for no apparent reason, it is advisable to consult your doctor to check for any potentially serious illnesses.
