Signs, symptoms
When a person has neurodermatitis, the person is likely to notice several of these signs and symptoms:
Itch: Neurodermatitis causes an itchy patch on the surface of the body. Unlike eczema, psoriasis, and other itchy skin conditions, people tend to develop just 1 or 2 patches that itch. While rare, neurodermatitis can cause several itchy patches.
When people develop neurodermatitis, they often find themselves:
- Scratching or rubbing the itchy patch(es), either frequently or sporadically
- Thinking that the patch(es) itches for no apparent reason
- Feeling itchiest while relaxing
- Feeling especially itchy when life becomes stressful
Pain: Some people feel pain. One study found that when neurodermatitis appears on the scalp, it may cause pain, itch, or both.
Raised, rough patch that is red to violet-colored: As the person continues to scratch or rub the itchy patch, a scaly, reddish to violet-colored patch appears.
Skin thickens and looks leathery: With frequent scratching or rubbing, the skin can thicken. The patch may look leathery and turn a brownish color. Very thick skin can have a grayish hue.
Hair loss: The scratching (or rubbing) can cause hair loss on areas like the scalp.
Open sore that bleeds: Repeatedly scratching or rubbing can wound the skin, leading to an open sore that bleeds. If this happens, the person has an increased risk of developing an infection.
Scarring: If a wound is deep, the skin may scar as it heals.
Infection: Signs of infection include honey-colored crusts and fluid leaking from the area. You may also see pus-filled bumps.
Some people are more likely to develop neurodermatitis. You can find out if you have an increased risk by going to Neurodermatitis: Who gets and causes.
