About Prurigo Nodularis

Prurigo Nodularis is a skin disease characterized by multiple, intensely itchy skin eruptions in symmetrically distributed areas of the extremities. The main symptom is prolonged, repetitive, and uncontrollable rubbing, scratching, and uncontrollable itching which leads to eroding papules and nodules on the skin. It is difficult to treat and entails a high disease burden.
