A child has a red rash under his armpits. What does it mean, causes, treatment

We asked Bulat Yunusov, a surgeon at GMS Hospital, to tell us why armpits can hurt and what to do about it.

The armpit area is a very sensitive area. Sweat glands are located on thin, delicate skin, and underneath are lymph nodes, an artery and a vein, several nerves of the brachial plexus, and muscles. Any damage or inflammation immediately leads to pain. In most cases, armpit pain is not dangerous in the long term, but in some cases it can be a warning sign from the body.

The pain can be one-sided or two-sided. Pain can be caused by a process that occurs in the armpit area, or it may be a consequence of a disease in another part of the body or organ.

Causes of rash in the armpits

A pediatrician or dermatologist will help determine the main cause of armpit rash in children. It is important to consult a doctor in a timely manner, undergo examination and begin treatment. In some situations, it is enough to follow certain recommendations to get rid of the problem.

A rash under the arms of a child is most often caused by the following reasons:


Name Description
FungusA disease in which infection of the body often occurs in public places. An easily transmitted pathology, therefore, to eliminate it, doctors prescribe antibacterial agents to patients. Without timely treatment, the fungus attacks healthy organs and tissues.
AllergyOften, a rash in the armpits of children is a consequence of the use of hygiene products. In some situations, even a simple nourishing cream can lead to rashes on the body.
Skin chafingThe skin in the armpits of children is hypersensitive. Damage can be easily caused by tight and uncomfortable clothing. Irritation provokes inflammation and leads to the appearance of rashes under the arms. This is facilitated by excessive sweating, uncomfortable and tight clothing. Wet skin becomes irritated faster. Rubbing rashes appear more often in spring or summer.
Heat rashA disease of the body that is characterized by an abnormal response to high temperatures and stressful conditions. The pathological condition can also appear after consuming hot foods and drinks. Warm rashes under the arms are small in size, red in color, and slightly raised in shape. It occurs more often during hot periods.
EczemaA chronic infectious disease is accompanied by a strong inflammatory process. Rashes appear on the child’s body and peel. The skin tightens and becomes covered with ulcers. In some situations, blisters form and cause severe itching.
Seborrheic dermatitisA chronic skin disease that occurs when a specific fungus enters the body. The inflammatory process negatively affects the functioning of the sebaceous glands. Not only rashes appear, but also redness. The skin swells, becomes oily, and is bothered by itching and burning. In some situations, yellow or white flakes will form.

Contact dermatitisThe pathological condition appears after contact with allergic substances. This can be regular soap, body lotion or cosmetics. The same thing happens when wearing clothes made from synthetic material. Contact dermatitis develops after fragrances and detergents. The pathology provokes the appearance of red and itchy rashes on the child’s body.
RingwormA disease characterized by scaly rashes that become crusty. In some situations, pathology provokes the appearance of red and round spots. Associated symptoms may include hair loss, severe itching, and blistering.
FurunculosisA purulent rash appears on the body. They cause painful discomfort to the child. Treatment is strictly carried out under the supervision of a doctor, since a complication of this disease is blood poisoning. In difficult situations, the patient is indicated for surgical intervention to open and remove the contents of the boil.
PsoriasisChronic pathology of non-infectious origin occurs with itching and peeling of the skin, its thickening is observed, and crusts form. A rash appears in the armpits with red spots of heterogeneous color.

Every disease or pathological condition is accompanied by associated clinical symptoms that cannot be ignored. A timely visit to a pediatrician or dermatologist will help determine the underlying cause and undergo treatment. Otherwise, there is a possibility of developing serious complications (secondary infection, scar formation).

What is diaper rash?

Diaper rash of the skin of a newborn is an inflammation of the skin folds that appears as a result of friction of the skin surfaces in contact with each other, as well as as a result of the irritating effect of skin secretion products and the negative effects of certain external factors.

One of the most common locations for diaper rash in a newborn's skin is the armpits. Due to the fact that the skin of the armpits is very thin and sensitive, active friction between the skin occurs, and little air gets into this area; diaper rash in this area bothers a large number of babies and, of course, their mothers.

Other Possible Causes

There are other provoking factors that cause armpit rashes in children:

  • bacterial pathologies (scarlet fever);
  • viral lesions of the child’s body (measles, chickenpox, mononucleosis);
  • a bite of an insect;
  • dermatological diseases;
  • failure to comply with simple hygiene rules;
  • increased sweating;
  • scabies;
  • chronic pathologies of internal organs in the child’s body;
  • hormonal imbalance;
  • severe obesity;
  • use of certain medications.

Children often encounter heat rash in the first years of their lives. The disease is characterized by the appearance of small pink blisters.

A rash under the arms of a child is not only accompanied by itching, redness, but also a burning sensation and pain. In some situations, bumps form at the site of the lesion, and clear or yellow discharge appears. In the absence of timely treatment, pathological processes progress and spread to healthy areas of the body.

What to do if a pimple in the armpit area hurts?

In addition to aesthetic discomfort, the rash may be accompanied by itching, burning, and pain. If a pimple in the armpit area hurts, you should consult a dermatologist to find out the cause of its occurrence. Sometimes acne can be combined with hidradenitis, and the doctor will prescribe complex treatment for different areas. To combat mild to moderate acne, your doctor may recommend azelaic acid, for example, Azelic®9 gel.

This is a drug that helps reduce the level of free fatty acids and normalize keratinization processes5. Azelik® gel exhibits antimicrobial activity against Propionibacterium acnes and Staphylococcus epidermidis5. The anti-inflammatory effect of the drug is based on the ability to reduce the metabolism of neutrophils and their production of free radical forms of oxygen5.

Diagnostic measures

A specialized specialist will help you determine the root cause and make the correct diagnosis. It is impossible to independently determine the source of the violations; it is strictly forbidden to give children medications without a doctor’s prescription.

A pediatrician or dermatologist examines the patient and, if necessary, prescribes additional tests:

How to distinguish heat rash from allergies in a newborn

Seeing any rash on the skin of a newborn, a nursing mother first of all begins to worry whether she has eaten something forbidden, which has led to an allergy in the baby. In a panic, she may refuse all possible allergens, including foods necessary for the body, and this, together with stress, can have a bad effect on lactation. If the baby is bottle-fed, then he doesn’t need an unreasonable change of formula due to suspected allergies. Therefore, before making any decisions, any skin symptoms should be shown to a doctor to clarify the diagnosis.

Before visiting a doctor, take a look at what the rash looks like and where it is located, this will help determine the nature of its origin.

What does diaper rash look like under the armpits?

There are 3 degrees of diaper rash in the armpits of infants, which develop gradually:

  • I degree - moderate hyperemia (redness) of the skin without visible violation of its integrity;
  • II degree - bright red inflammation, sometimes accompanied by erosions;
  • III degree - weeping areas of inflamed skin that appear as a result of numerous erosions merging with each other; the formation of ulcers is also possible.

At this degree, erythema extends beyond the armpits and can affect the skin of the chest and upper extremities.

Most often, the addition of bacterial or fungal flora occurs precisely with the third degree of diaper rash. Signs of a bacterial infection include severe hyperemia with discharge, blisters and pustules with white or yellowish contents.

Preventive measures include observing rules of skin hygiene and eliminating irritating factors that contribute to the development of diaper rash in newborns.

Prevention of diaper rash in the armpit skin consists of:

  • cleansing the armpit area with running warm water. If it is not possible to wipe with water, you can use wet cleaning wipes without alcohol or fragrance. A number of studies have shown that the use of such wipes is effective for cleansing and hydrating the skin, as is bathing in water using fabric washes;
  • bathing the baby in water with the addition of high-quality washing products, pharmaceutical brands approved by dermatologists;
  • using frequent air baths after bathing the child;
  • using a barrier care product or water-repellent emollient after swimming;
  • using high-quality fabrics and materials when choosing clothes and diapers for a newborn;
  • eliminating moments of skin trauma in the armpit area;
  • using high-quality products for washing children’s clothes, without chemicals, parabens and other undesirable components.
