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 blood vessels keep your underarms warm and the sweat glands ensure it is regularly damp. This causes your armpit to be an ideal location to develop itchy conditions. But, more importantly, itchy underarms are a potential indicator of bigger health problems like breast cancer, psoriasis, and cancer.
