Prurigo nodularis, or PN, is a skin disease that causes hard bumps, or nodules to form on the skin. These nodules are extremely itchy and can itch constantly. Many people scratch themselves to the point of pain or even bleeding due to the intense itch. Unfortunately, itching the bumps can cause more of them to appear, escalating the vicious cycle.
What causes prurigo nodularis?
While the exact cause of PN is unknown, certain risk factors may make you more prone to developing PN. Some of these include:
- A history of skin conditions that cause itching, such as eczema
- Reduced liver and kidney function
- Type 2 diabetes
- HIV/immunodeficiency
- Some psychological conditions
What exactly do the nodules look like?
The nodules can vary in size. You may have some that are very small and some that are rather large. They typically have a dry, rough top and typically appear on areas like the arms, shoulders, and legs. You may notice a few nodules, or a few hundred.
Is prurigo nodularis genetic?
Prurigo nodularis is not believed to be an inherited disease. If one of your parents has PN, this does not mean that you will develop it. However, since the development of PN is sometimes associated with having other health problems or skin diseases, you may notice a family history associated with those skin conditions.
How is prurigo nodularis treated?
While some treatments to reduce itchiness are available, they don’t work for everyone. Many people with PN may have to try several different treatments without receiving much relief due to the intense itch that comes with PN. Fortunately, if you have prurigo nodularis, you may be eligible for currently enrolling research studies to help find potential new PN treatment options.
