Hi. I started to develop a quarter sized red mark on my neck. I figured it was from a shirt maybe rubbing against the skin, however, now a week in it has not heeled and has turned into a dry red mark/scab. Furthermore, I developed a similar red mark on my cheek. It started just being red then the top layer of skin peeled away. Now it is a quarter sized redmark that is very dry, it doesn t feel like normal skin to the touch.
