In brief: ARMPIT ITCHING

If your armpit is itching, and if you are scratching to relieve the itching, it may be that you are scratching too hard.
Thts's why the blood. The itching might be due to an underarm deodorant, a new soap, laundry detergent, and new shirt or sweater or blouse. If it continues to itch, see a dermatologist. And don't scratch!
