Prurigo nodularis (PN) is a chronic skin condition that is characterized by very itchy, hard, and typically painful nodules on the skin. PN can have a significant impact on a person's quality of life by causing discomfort, sleep disturbances, and emotional distress. PN is not infectious but can result in severe skin damage and scarring due to repeated itch-scratch cycles over a period of time.
Causes of Prurigo Nodularis
The exact origin of prurigo nodularis is still unclear, but it is regarded by scientists as being caused by a combination of nerve impairment, immune reaction, and chronic inflammation of the skin. Several factors can contribute to PN development, including:
- Persistent Scratching and Itching – Repeated scratching leads to nodules to thicken, continuing to feed the itch-scratch cycle.
- Underlying Health Conditions – PN is generally associated with systemic conditions like eczema, psoriasis, diabetes, liver disease, kidney disease, and HIV.
- Neurological Factors – Abnormal transmission of nerves can be a causative factor in itch sensation as well as in PN development.
- Allergic Reactions – Some individuals may develop PN as a result of allergic reactions to environmental factors.
- Psychological Stress – Stress, depression, and anxiety can exacerbate symptoms of PN and increase the severity of itch.
Symptoms of Prurigo Nodularis
Prurigo nodularis is seen as multiple hard nodules that are dome-shaped or warty and vary in size and color ranging from skin-colored to red to brown to dark spots. The symptoms are:
- Intense Persistent Itch – The PN itch is severe and tends to worsen at night with constant scratching.
- Hard Nodules on the Skin – These can appear anywhere on the body but mostly appear on arms, legs, and trunk.
- Scarring and Skin Thickening – Itching repeatedly can lead to hardened, uneven skin that becomes colored.
- Discomfort or Burning – Some individuals experience more than itching discomfort, including a stinging or burning feeling.
