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.
Keep in mind that itching due to yeast infection is similar to the same itch felt with several other health conditions, such as trichomoniasis (an STI) and bacterial vaginosis, a bacterial infection of the vagina.
