Prurigo nodularis is a condition where repeated scratching or picking at a site creates itchy, raised, hard bumps on the skin. Prurigo nodularis can appear anywhere on the body, but is most commonly found on the arms, legs, trunk, or buttocks. The condition is more common in older individuals (over 50), Blacks, and those with certain long-term diseases (eczema, diabetes, kidney disease, Hepatitis C, HIV). Treatment involves breaking the itch-scratch cycle. Antihistamines, topical medications, and intralesional steroid injections are commonly used therapies.
