Why is Eczema itchy?

An “itch that rashes” is what eczema is referred to many times. In eczema, the origin of itch lies in the skin. As we know that the people suffering from eczema are super sensitive, their immune response becomes hyper for even a small encounter. This interaction stimulates the nerve ending called C fibers which lies in the top layer of the epidermis. This nerve ending, in turn, stimulates the nerve fiber sending a signal to the brain resulting in itch.
