My underarms have been really sore, and itchy, for months now. I thought it was my deodorant. I used dove, it was peeling and stuff then, I finally changed to a natural deodorant, it s just been sore and itchy. Recently shaved it and cleansed it with alcohol, and it turned white for a couple minutes then went to a grey and finally my skin color (I m African American). What is going on?
