Conditions such as impetigo and eczema can lead to itchy underarms during pregnancy. Furthermore, most women are vulnerable to yeast infections which can also cause armpit itch.

Breast cancer, especially the inflammatory breast cancer can also a cause of not only an itchy breast but also an itchy underarm area or an itchy patch near your armpit i.e. “itching can be a sign of breast cancer” [cancerresearchuk.org]. Since a “tail of breast tissue extends up into the armpit” [patient.info], you are likely to end up with an itchy underarm.

If inflammatory breast cancer is behind your armpit itching, you will have itching armpits cancer symptoms such as swollen, sore, red and warm breasts, “the skin may appear pitted like an orange peel, and n1pple changes such as inversion, flattening, or dimpling may occur” [nationalbreastcancer.org].

Finally, lymphoma, a type of cancer that affects lymphocytes found in lymph nodes. “Lymphoma can sometimes cause an itchy rash… reddish or purple scaly areas…in skin folds” [healthline.com] including on your armpits.

4. Psoriasis

9. Fox-Fordyce Disease

Affects mainly young women aged 13 to 35 years but can affect even anyone. It is characterized by small itchy bumps due to clogged sweat glands especially on underarm and groin areas. It can be treated as hidradenitis suppurativa.

10. Poor hygiene

When sweat and dirt mix together, they can form a perfect breeding ground for bacteria that is normally found on your skin. This could result in underarm itch.

11. Excessive sweating (hyperhidrosis)

Encourages overgrowth of bacteria and other microbes as it provides a moist and damp environment. These microbes and bacteria overgrowth can irritate underarms and make them itchy.

12. Dry itchy armpits or xerosis

Besides the above, other reasons why you get underarm itch include armpit folliculitis (inflamed hair follicles when they get infected by bacteria), tinea axillaris (armpit ringworms), Miliaria Rubra, insect bites, irritated or inflamed underarm glands, heat rash, sweat rash,  cellulitis, enlarged lymph nodes, some deodorants and antiperspirants, pinworm, scabies, stress, intertrigo, among others.

Furthermore, any other disorder that makes your skin to itch can also cause your armpit itch. Kidney and liver disease, medication side effects, intestinal or skin parasites, internal cancer, senile pruritus or allergies to bra material (especially rubber, latex or nickel) among others can also be responsible for this problem.

Itchy armpits no rash or itchy underarms no rash

Whereas most armpit itchiness is accompanied with a kind of rash, it is possible to have itchy underarms with no rash. There might be a rash but not visible with naked eyes, especially when it is very mild. So, what causes itchy armpits with no rash?

If you have itchy underarms without any rash, some of the common causes of itchy armpits or groin with no rash include mild allergies (to deodorants, antiperspirants and other allergens), axillary hyperhidrosis i.e. “excessive sweating of the armpits (known as axillary hyperhidrosis) can cause itchy skin without rashes” [suite.io], lymphoma cancer type i.e. “cancer will cause the skin to become itchy without a rash, weight loss, fever, swollen lymph nodes and fatigue” [newhealthguide.org], dry skin, scabies, among other causes.

  1. An itchy armpit can be an irritating and sometimes disruptive condition. While not normally serious, the underarm region is unfortunately prone to dermatological conditions of one form or another.

    This is in part due to how the armpit is a rather unique part of the body. While on the surface it appears little more than folds of skin and some hair, the armpit contains a large number of blood vessels, lymph nodes, and sweat glands.
