Hello. I have recently started developing thick scabs under
my left armpit
. They started out as itchy, with no physical signs of scabbing or anything. Then, almost overnight, a layer of what feel like scabs popped up. And they are very painful to the touch. It has been about two weeks now, and the "scabs" have spread over most of my armpit,gotten thicker, and oddly enough, a smaller scab is popping up under the other armpit which is starting to spread!
