What Does Prurigo Nodularis Look Like? Understanding Chronic Itchy Skin
Chronic itchy skin, particularly prurigo nodularis, is a condition that manifests as intensely itchy nodules or bumps on the skin. These nodules are often the result of prolonged scratching or rubbing, which leads to the formation of thickened, raised lesions. The appearance of these nodules can vary significantly from person to person, but they generally share common characteristics that help in identification. The condition is not contagious but can be incredibly frustrating for those affected, as the itching can be severe and persistent. Appearance of Prurigo Nodularis The nodules associated with prurigo nodularis are typically small, ranging from a few millimeters to a centimeter in diameter. They are often dome-shaped and may have a rough or scaly surface. The color of the nodules can range from pink or red in lighter skin tones to brown or black in darker skin tones. Over time, the constant scratching can lead to hyperpigmentation or hypopigmentation, altering the skin’s appearance further. The nodules are usually distributed symmetrically on the body, commonly appearing on the arms, legs, back, and abdomen. Causes and Triggers While the exact cause of prurigo nodularis is not fully understood, several factors are believed to contribute to its development. These include underlying skin conditions such as eczema or dermatitis, systemic conditions like kidney or liver disease, and psychological factors such as stress or anxiety.
