pruritus

 [proo-ri´tus]
an unpleasant sensation of the skin, provoking the desire to scratch or rub it; called also itching. adj., adj prurit´ic. It is common in many types of skin disorders, especially allergic inflammation and parasitic infestations. Systemic diseases that may cause pruritus include diabetes mellitus (pruritus vulvae) and liver disorders with jaundice. Hemorrhoids are often accompanied by rectal pruritus. Emotional distress plays an important role in the development and control of this disturbing symptom. Unless pruritus is relieved the patient may become exhausted from lack of sleep. Cleanliness, soothing ointments or lotions, sodium bicarbonate baths, and sometimes tranquilizing drugs are used in the relief of pruritus. Since it is a symptom of some other disorder, complete cure of pruritus depends on control of the primary illness.

A. Have you tried to change your diet? Coffee, tea, cola, chocolate, tomatoes, and citrus fruits may cause itching in this area (termed anal pruritus). You can try to avoid these foods and to keep a log of the itching sensation to see what helped. Apart from that, consulting a doctor is usually necessary.
