itch

The physical sensation is characterized by an irritating, prickling feeling that demands a tactile response. It is often associated with allergic reactions, dry skin, or healing wounds, creating a cycle of irritation and relief through scratching. When used to describe a psychological state, the word shifts toward a sense of restlessness or an impulsive urge. This usage typically describes a craving for change or a specific activity that cannot be ignored, often appearing in the phrase "itch to do something."
