Causes of underarm rash

Harmful Chemicals

The most common is allergic response to some chemical that you have applied on the skin,  which may include deodorants, perfumes or soap.  Rough clothing and detergents can also be a cause for itchy armpits.  This can give rise to contact dermatitis

Fungal Infection

Your underarms are a breeding ground for  fungus, just like other moist parts of the body like the groin.  Not keeping the area clean can cause rash under your  armpit. There are various types of fungal infestations; a dermatologist would be in the right place to advise a good quality anti-fungal cream to take care of this cause.

Folliculitis

Red armpit rash with pain and bumpiness is the cause of folluculitis. These often have an appearance of a pimple. One of the reasons that can trigger this is shaving; this activity can deteriorate the hair follicles and exacerbate the condition.

Other causes

There can be other conditions that can be attributed to itchy armpits including scabies, diabetes, syphilis and even HIV rash.

Rash Under Armpit – Treatment

In most cases, the rash will disappear but if the underarm itching increases, then you have to visit a doctor who will give you prescription medication depending on the cause.

Calamine lotion is a good topical application for rash under armpit caused by contact dermatitis. If the itching is severe, the doctor may prescribe a hydrocortisone cream that may be applied 2 to 4 times a day.   If the cause for underarm rash is a fungal one, then the doctor will not advise a hydrocortisone cream because it can worsen the condition.

It is important to break the scratch-itch cycle; this can be done with the help of an oral antihistamine which your doctor will prescribe.  In many cases, these antihistamines are known to cause sleep or drowsiness.  If there is pain in the armpit due to the rash, the doctor may prescribe an ibuprofen  or any other pain-killer to ease the inflammation.
