What is an Armpit Rash?
Pruritus or an armpit rash is a skin condition where the skin of the underarms become reddened and scarred due to an infection. The condition is also accompanied by the growth of lesions in the regions that cause irritation and pain. Underarm rashes are particularly very uncomfortable and itchy as they remain covered and enclosed most of the time, thus alleviating the symptoms and making it difficult to achieve a relief quite easily. A burning sensation may also accompany the armpit rashes and the symptoms tend to enhance with time if not treated.
Armpit rashes may occur in both men and women and may affect people of various age groups, including children and infants. Though usually benign, they may lead to complications sometimes.
Symptoms of Armpit Rashes
Much like other rashes, underarm rashes also exhibit a number of familiar symptoms that may be listed as below:
Eruptions:
Armpit rashes are typically characterized by small, pimple-like eruptions that spread all over the skin in the affected area. These eruptions can be white or red depending on whether they contain pus or not and cause pain when touched or rubbed.
Itching:
Itching is a common symptom of underarm rashes. Irrespective of the causal factor, armpit rashes usually itch quite a lot, making the sufferer quite uncomfortable. Though scratching the area may offer instant relief, the feeling is temporary and it may also worsen the pain.
Irritation:
The swelling, as well as the constant itching of the rashes, gives rise to irritation. Inability to scratch the area may ramify the situation while scratching the area from time to time may give rise to a burning sensation under the arms.
Reddening:
The infection causing the rashes often makes the particular area red and gives a blotchy appearance.
Blisters:
When left untreated for a prolonged period, rashes may develop blisters that are filled with clear fluid.
Scaling:
The infection may also cause the skin to flake out, thereby making it scaly and rough.
Cracking:
Infection of the armpits may also cause the skin in the area to develop cracks that are painful.
Tenderness:
The infection combined with the constant itching may cause the area to become tender that emits pain even on touching.
Bleeding or Bruising:
Prolonged scratching of the infected skin may cause bleeding in the area or make the skin bruised.
Causes of Underarm Rashes (Armpit Rashes)
Since the armpit remains covered and folded most of the times, infections of different types easily spread in the underarms area. These infections lead to rashes that become itchy and cause irritation to the person unless some sort of treatment procedure is followed. The main reasons that lead to the occurrence of armpit rashes are as follows:
1. Poor Hygiene:
One of the most common causes of armpit rashes is unhygienic practices. The underarms area needs to be washed and cleaned regularly and kept dry and soft at all times. If this doesn’t happen or the skin is continuously exposed to harmful chemicals, rashes may develop and spread in the armpits.
2. Miliaria Rubra:
Commonly known as heat rash, miliaria rubra is a skin condition that develops mostly during the hot summers. This type of infection is caused by the harsh weather conditions and can occur in people of all age groups. However, children are more at risk as they have underdeveloped sweat glands.
3. Auxiliary Hyperhidrosis:
Excess production of sweat by the sweat glands is referred to as auxiliary hyperhidrosis. Not only does the condition creates bad odor and embarrassing staining of clothes, excess sweating keeps the underarms moist at all times, thus making it the breeding ground for bacteria that can cause rashes and itches.
4. Axillary Lymphadenopathy:
The enlargement of the lymph glands located in the armpits may also cause rashes and itching. The condition is mainly known as Axillary Lymphadenopathy and is usually benign. However, the lump caused by the enlarged lymph glands usually cause irritation and infection which lead to armpit rashes. However, if the swelling is too big or doesn’t decrease in size even after a long time, it may indicate malignancy that needs immediate medical attention.
5. Axillary Folliculitis:
A bacterial infection caused by Staphylococcus aureus can also cause rashes in the underarms. The bacteria affect one or more hair follicles of the armpit and cause the area to swell and become full of abscess which gradually becomes itchy. Big swellings can also cause scarring.
6. Hidradenitis Suppurativa:
An infection and inflammation of the sweat glands in the armpit may lead to the formation of lesions on the skin. These lesions are usually caused due to the constant friction of the underarm area and may become large and cause pain and rashes. It is a chronic condition and itching of the area may lead to further ramifications. When the lesions burst, scarring may occur.
7. Inverse Psoriasis:
Inverse psoriasis mainly affects skin folds, including the armpits. The condition is characterized by excessive growth of skin cells in a particular area that makes it thick and scaly which causes itching and rashes. More commonly occurring in people with obesity, inverse psoriasis or flexural psoriasis can be painful and cannot be completely cured.
8. Ringworm:
Cause by dermatophyte, a fungus, ringworm is a fungal infection that causes scaly and dry skin accompanied by circular lesions. The rash usually has shifts of broken hair along with inflamed and clear skin at the center.
9. Dermatitis:
Another common cause of the rashes could be dermatitis. It is a skin condition where the skin becomes inflamed and is accompanied by lesion and itching. Dermatitis mainly occurs if the skin is hypersensitive and may often be inherited. According to the causal factor, dermatitis can of the following types:
- Atopic Dermatitis
This type of rashes usually develops during childhood. Commonly known as eczema, this type of rash not only affects the areas of the armpit, but also can occur on the rear portion of the knees, the inner folds of the elbow, etc. Eczema is usually characterized by itchy, red and crusting skin. Bleeding can also occur because of the intense itch that accompanies eczema. The rashes may sometimes produce a type of clear fluid. Though the skin remains normal during most of the year, flare-ups occur during certain periods of the year, making the situation extremely uncomfortable.
- Seborrheic Dermatitis
It is a type of skin irritation that occurs partly due to excess production of skin oils. This type of rashes is quite unlike those of eczema. While eczema patches are dry, these patches appear to be oily. The scales may also turn yellow or white due to the presence of excess oil in the area. Seborrheic dermatitis may also occur in the form cradle cap in infants and usually affects different areas of the body above the shoulders, including the armpits.
- Contact Dermatitis
Contact dermatitis mainly occurs due to direct contact with an irritant or allergen. Use of lotion or deodorant containing allergens may cause rashes under the armpit. Contact dermatitis can also be caused due to an irritant in your laundry detergent, clothing fabric, etc.
- Candida
Candida is a common yeast or fungal infection that affects parts of the body that remain moist during most times, including the armpits. Candida causes rashes, itching, swelling and scaling of the skin and can worsen during humid or hot weather, due to tight clothing or as a result of unhygienic habits. However, unlike other types of armpit rashes, candida needs to be treated with an antifungal cream and not steroid creams.
10. Shaving
Shaving of the underarms could also be a reason for the development of armpit rashes. Since, armpits remain mostly covered and away from the sun, the skin in the area is usually much more sensitive than other parts of the body that are commonly shaved. As such, the blunt edges of a razor may cause irritation to the sensitive skin that may lead to the break of rashes. Rashes may also occur due to ingrown hair and razor bumps in the underarms.
11. Friction
Wearing tight dresses may also be a causal factor. If the fabric isn’t quite suitable for the skin, constant friction against the fabric for long periods could cause rashes in the underarms.
12. Pregnancy
Mild cases of underarm rashes are often seen during pregnancy, predominantly in the first three months. Though this is usually a common occurrence and no special treatment is needed, in certain cases, the rashes may worsen gradually and this needs special medical attention. Delay could prove to be fatal.

Apart from these, armpit rashes may also be caused as a symptom of other severe diseases that need quick medical treatment. For example, people undergoing anaphylaxis or allergic purpura may develop a rash and are in need of proper medical care at the earliest possible. These ailments are quite serious and not treated on time, may cause serious complications.
Diagnosing Armpit Rashes
Diagnosing the causal factor of armpit rashes is extremely important before opting for any curative process.
