Itch armpits might mean different things including effect of armpit shaving, infections (yeast, bacterial or viral infections), cancer, pregnancy, among others. Itchy underarms can be accompanied with rashes or no rashes, redness, swelling, etc.
The cause is unknown; the perspiration is not due to anxiety or stress. Irritant contact dermatitis: Skin inflammation (redness, swelling, pain, or heat) caused by an irritating substance touching the skin. Soaps, deodorant, alcohol, and dry air may all cause irritant contact dermatitis of the armpit.
