It can torment the patient and cause discomfort, stress, loss of sleep, concentration difficulty, and constant concern. Itching can take place in the whole body or in some specific body part. Itching, known medically as pruritus, has a great variety of possible causes. It may accompany various skin diseases such as hives, eczema, contact dermatitis (allergic reaction to materials contacting the skin), insect bites, prickly heat ,and scabies.

Itching is a tingling or uneasy irritation of the skin that makes you want to scratch the affected area. When itching is generalized and persistent, medical help may be needed to determine and treat the cause.Generalized itch, for obvious reasons, is more difficult to treat. Itches can also occur with or without skin lesions (e.g., bumps or blisters). An uncomfortable sensation in the skin that feels as if something is crawling on the skin or in the skin , and makes the person want to scratch the affected area.

Many drugs, including barbiturates (sleeping pills), can cause itching.

Itching, also called pruritus, is an unpleasant sensation of the skin that causes a person to scratch or rub the area to find relief. Generalized itching can accompany some internal diseases, and sometimes may be the only troublesome symptom. Among such diseases are gallbladder disease and uremia (often associated with hyperparathyroidism, or excessive functioning of the parathyroid glands in the neck area).Severe scratching can injure the skin causing redness, bumps, and scratches. Injured skin is prone to infection. Itching instinctively leads most people to scratch the affected area. Different people can tolerate different amounts of itching, and the threshold of tolerance can change due to stress, emotions, and other factors.
