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.
Tell your doctor right away if you have signs of yeast infection in the vagina (such as unusual vaginal discharge/burning/itching/odor) or in the penis (such as redness/itching/swelling of the penis, unusual discharge from the penis).
