hi i'm a 17 year old girl and my right nipple has been itching for the past two days. the itching has gone away but there's this rough dry skin around my nipple that won't go away.and its only on one nipple not both.  i tried coconut oil and vaseline but they didn't work:/ does anyone know what this could be???? I never had this happen before and I'm freaking out. please help.
