I have been noticing skin discoloration for the past several, I mean several months ago, on my chest, stomach, back, shoulders and now it has spread all up my neck. I sent a picture to my family Dr and he said I needed to go the ER now but I am wondering what could cause this and is this something I should be worried about? It's definitely not normal and I was I could attach a picture to show exactly what I am talking about. I'm scared and don't know what to do or expect.
