Eczema types: Neurodermatitis 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.
Neurodermatitis on the ankle and foot
Scratching the neurodermatitis can wound the skin, which may scab as it heals,
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.
Neurodermatitis with scarring (white lines)
Constant scratching of neurodermatitis wears away the skin. As the skin heals, it may scar as shown here.
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.
