These nodules are typically found on the arms, legs, and trunk, and can vary in size from a few millimeters to several centimeters. The condition is characterized by intense itching, which often leads to scratching and further skin damage. This cycle of itching and scratching can exacerbate the condition, making it difficult to manage.

Intense itching, especially at night
Thickened skin around the nodules
Scarring from repeated scratching
Possible secondary infections due to skin damage

Potential Causes
