Causes
By Mayo Clinic staffThe exact cause of neurodermatitis isn't known. Sometimes neurodermatitis begins with something that simply rubs or irritates the skin, such as tight clothing or a bug bite. As you rub or scratch the area, it gets itchier. The more you scratch, the more it itches.
In some cases, neurodermatitis is associated with other skin conditions — such as dry skin, eczema or psoriasis. Stress and anxiety can trigger itching, too.
