How To Treat Irritation In Your Armpit

Armpit irritation is a painful condition and may cause severe discomfort, particularly during hot weather. Irritation in armpits may occur for a variety of reasons. The most common cause is contact dermatitis, according to Verywell Health. It occurs when your armpit skin comes in contact with an irritant, such as a deodorant or perfume with strong chemicals. It may lead to a bright red rash, along with blisters. Another common reason for armpit irritation is when the folds of your skin have some type of fungi or bacterial development from the excess moisture (sweat) or lack of hygiene, explains Verywell Health. It may also cause a significant bright-colored rash, along with a serious burning sensation. This condition is also known as intertrigo.

Sometimes, armpit irritation occurs because of inflammation in the hair follicles, leading to constant irritation, per WebMD. This condition generally goes away on its own after a while. If the lymph nodes in the armpits become swollen or enlarged because of a tumor or cancerous growth, it may cause a condition called axillary lymphadenopathy. It's also a reason for armpit rash, warns WebMD.

How to get rid of armpit irritation

To get rid of an armpit rash, you may have to make some changes to your hygiene and lifestyle and seek certain medications to ease the irritation. Flo Health suggests taking regular baths or showers. This is particularly necessary if you have a tough outdoor job requiring physical work, you sweat profusely, or live or work in a hot environment. The site also recommends avoiding a bath with hot water, as it can trigger more irritation — instead, take a cold shower. Alternatively, Healthline says that applying a cool block of ice to the affected region in the armpit can soothe inflammation.

You may also want to try massaging the region with some rapid-action essential oils, per MedicalNewsToday. Experts recommend using coconut, lavender, or sunflower oil to treat the armpit rash. Simply dab a cotton swab in the oil and gently massage it for a couple of minutes. Healthline also advises people with skin irritation under their arms to consume more fruits with vitamin C (lemons, oranges, etc.), as they carry essential anti-allergic and anti-inflammatory compounds that help with skin infections.
