Itching: Skin Irritation Leading to Scratching

Itching (Latin: prurire = to itch) is an unpleasant sensory sensation that triggers the desire to scratch. The tormenting itch can occur anywhere: on the body, face, scalp, or in the genital area. It is triggered by nerve cells responsible for the sensation of itching. They raise an alarm when the skin is irritated from the outside or inside. Itching is often the leading symptom of many skin diseases such as eczema or neurodermatitis, but can also be triggered by internal diseases.
