Prurigo Nodularis

A chronic disease of intensely itchy nodules that is more than a scratching habit.

What it is

Intensely itchy, firm nodules

Prurigo nodularis is a chronic skin disease in which firm, very itchy nodules develop, often on the arms, legs, and trunk. The itch drives scratching, which worsens the nodules in a difficult cycle.

More than skin-deep. Prurigo nodularis involves immune and nerve pathways that amplify itch, and it is frequently linked to other medical conditions, so it deserves a full evaluation rather than being dismissed as a scratching habit.

Signs and symptoms

What it can look like

  • Firm, raised, very itchy nodules
  • Often on the arms, legs, and trunk
  • Symmetric, within reach of scratching
  • Thickened or scarred skin from chronic scratching
  • Sleep disrupted by relentless itch

Associated conditions

Comorbidities to know

Prurigo Nodularis can travel with other conditions, which is why whole-person assessment matters, not just treating the skin.

  • Atopic dermatitis. Often associated
  • Chronic kidney or liver disease. Can be linked to severe itch
  • Thyroid disease. An associated condition
  • Diabetes. More common
  • Mental health. Anxiety and depression, worsened by relentless itch

The burden

Why it matters to patients

The relentless itch and visible nodules disrupt sleep, mood, and daily life, and the scratch-and-itch cycle can feel impossible to break without help.

Care has expanded

There is more help than ever

Prurigo nodularis is treatable. Newer targeted therapies address the immune and itch pathways behind it, with treatment choices that require accurate diagnosis, severity assessment, and monitoring, along with a search for any underlying contributors.
