Prurigo nodularis (PN) is a chronic skin condition characterized by itchy bumps on the skin’s surface. Scratching these can lead to the formation of painful nodules. The condition’s exact cause is unknown, but several factors and underlying health complications can increase its susceptibility in people. The following are a few early warning signs of prurigo nodularis to help individuals identify the condition and seek prompt help from a skin specialist. Persistent itching One of the earliest signs is persistent itching. This itching can be intense and worsen at night. Since the symptom cannot be managed instantly, it impacts a person’s sleep and overall well-being. Skin nodules or papules As the condition progresses, small, raised nodules or bumps develop on the skin’s surface around the arms and legs, upper and lower back, and abdomen. These skin lesions are typically firm, reddish-brown, and vary in size from a few millimeters to centimeters. Superficial skin injuries People with prurigo nodularis often develop abrasions on their skin due to the relentless itching. These abrasions can range from small scratches to larger, more extensive areas of skin damage, depending on the severity of the condition. Scratching and burning sensation Chronic scratching may make the skin hardened, harsh, and hyperpigmented.
