Neurodermatitis starts with a patch of itchy skin, but scratching it makes the area even itchier. Eventually you may scratch simply out of habit. This cycle of chronic itching and scratching can cause the affected skin to become thick and leathery.
Neurodermatitis — also known as lichen simplex chronicus — isn't serious, but breaking the itch-scratch cycle is challenging.
Successful treatment of neurodermatitis depends on identifying and eliminating factors that may be aggravating the problem. Over-the-counter and prescription creams can help ease neurodermatitis symptoms.
Signs and symptoms of neurodermatitis include:
The primary symptom of neurodermatitis is itchy skin — often a single patch on the neck, wrist, forearm, thigh or ankle. Sometimes neurodermatitis affects genital areas, such as the vulva or scrotum.
The itchiness, which can be very intense, tends to come and go. Eventually you may scratch simply out of habit.
When to see a doctor
Neurodermatitis is a skin condition characterized by chronic itching or scaling. You'll notice raised, rough, itchy areas of skin — typically on the neck, wrist, forearm, thigh or ankle. ...
The 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.
Certain factors may increase your risk of neurodermatitis, including:
Persistent scratching can lead to a bacterial skin infection and permanent scars or changes in skin color. Scratching may also disrupt your sleep.
