Itching In The Armpits: Causes, Symptoms and Treatments

The causes of itching in the armpits, or in the armpit, as they say, may be allergy, ringworm, psoriasis, among other problems. Itching is an uncomfortable symptom that can sometimes linger, but is often a good indicator of a problem in the body. In addition to the already known skin diseases such as urticaria, psoriasis and eczemas, other causes that help explain the onset of itching are diabetes, constipation, urinary or bile salt retention, blood disorders, food poisoning and diabetes, in addition to certain types of tissue. In this article, we’ll explain what may be itching in the armpits and what you can do to get rid of it. Keep reading to learn more.


Allergies in the armpits

Several causes may have triggered the armpit allergy that is causing so much itching. The three main ones are:

  • Allergy to deodorant;
  • Allergy to the method of depilation (such as razor blade);
  • Allergy to tissues (usually synthetic, such as lycra, nylon and polyester);
  • Allergy to past creams or perfumes in the region (moisturizers and sunscreens, for example).



When using razor blade for the depilation of the body, it is common that when the hairs are growing again, feel an itch in the place that has been shaved. In this case, the itching does not indicate disease or type of illness

  • Contact dermatitis: Like an allergy, contact dermatitis is an inflammation of the skin that appears when it comes in contact with the irritating agent. To relieve it, it is recommended to pass an itchy ointment under the armpits until the redness and itching pass, and obviously avoid getting in contact with the product causing the irritation again.
  • Atopic dermatitis: Atopic dermatitis is not a type of allergy and does not depend on an irritant to trigger it. Generally, its cause is genetic. It may arise from one day to the next, without explanation, and may be chronic. Regions of “folds” in the body – such as the armpits – are more prone to be affected by contact dermatitis.




If you have an intense underarm itching, be sure to consider the possibility of psoriasis. Psoriasis is a chronic disease of unknown causes. It is characterized by redness and scaling of the skin. Psoriasis can reach the scalp and extremities of the body such as armpits, elbows, back and knees. Symptoms of psoriasis include itching, redness, pain and burning sensation. Psoriasis patches appear red, covered by whitish scales. The disease has no cure, but with proper and regular treatment the patient has the condition of life virtually unchanged.



It should be borne in mind that most skin conditions (except allergies and contact dermatitis) are chronic and may remain asymptomatic for a long time. When they give the faces, it is worth considering the possibility of being only psychosomatic of some psychological condition. If you are very stressed, have recently been traumatized, abstinent from drugs, or have illnesses such as depression, anxiety, bipolar disorder, panic syndrome, or eating disorders (such as anorexia and bulimia, for example) for your case. It can make all the difference at the time of diagnosis.




People who have a high sweating tend to be more propitious to developing underarm fungi. In addition, people who already have ringworm in some other part of the body are more likely to report the onset of the disease in the armpits. Lastly, patients with vitamin deficiency and celiac disease are also more prone once the immune system is weakened. Read How to get rid of ringworm?



Symptoms of mycosis in the armpits:

  • Itching in the armpits, burning and redness;
  • Circular lesions with scaly and dry skin;
  • Possible odor emanating from the armpits;
  • Dimming of the affected region;


For treatment, oral antifungal medications or topical ointments are ideal. Evaluating according to the degree of mycosis (and how much it has already spread), the doctor will be able to indicate the ideal treatment for your case.



To prevent the onset of mycosis, avoid clothing of synthetic fabrics, wash all your clothes, bedding and towels with hot water to kill all micro-organisms and do not share personal objects. Talk to your doctor about the best deodorant to use in this case and discuss the possibility of taking vitamin supplements to suppress immune deficiencies.
