Nodular prurigo

Prurigo nodularis, also known as lichen nodularis, is a chronic skin disease characterized by itchy nodules and is more common in adult women. This disease is similar to the "horse stable" recorded in the medical literature of the motherland. For example, "The Sources of Various Diseases" records: "For horses, the flesh is hidden as the root, and the pain is not known." The old doctor Zhao Bingnan called the disease "stubborn wetness."
