I have this weird skin rash that began on my neck and has spread to my face and shoulders as well. When it was just on my neck I thought it was dry skin, because I have had dry skin there before, but as it has spread to my shoulders and face it has turned into red itchy inflamed bumps. I have not been using any new kinds of cosmetics or soaps or detergents lately, and have no idea what could have caused an allergic reaction.
