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.
Consider other causes of armpit rash. These may include allergies to food and medication, poison ivy or poison oak, insect bites, or an autoimmune disorder such as psoriasis. Viruses such as flu or chicken pox can also cause rashes. Consult your physician if you suspect any of these as reasons for underarm inflammation.
