Pruritus
Itching (pruritus) is an unpleasant sensation that compels a person to scratch the affected area. Itchy skin is usually just an annoying but temporary problem, and rarely indicates a serious underlying cause.
An itch is often caused by a condition affecting the skin, but it can be a sign of a more serious underlying problem. In some cases, it may not be possible to identify a specific cause. Itching is sometimes caused by an allergen, irritant or another environmental factors.
The best treatment for itching depends on the cause. Some lotions, creams and medications available over the counter from pharmacies or on a prescription from your GP can help reduce itchiness.
