Symptom

Itching

Itching (pruritus) is an unpleasant sensation that creates the urge to scratch. It can occur locally or all over the body, intermittently or continuously.

Local itching may be caused by rash, fungal infection, insect bites or contact irritation. Generalized itching without visible skin symptoms may indicate internal causes such as liver disease, kidney disease or thyroid dysfunction.

Treatment depends on the cause. Moisturizing creams and antihistamines help with mild itching. Persistent or severe itching always requires a doctor's assessment.

Frequently asked questions

What causes itching without a visible rash?

Itching without a rash can be caused by dry skin, allergy (for example a drug reaction), liver or kidney disease, thyroid dysfunction or neurological causes. Stress and psychological factors can also cause itching. A doctor will examine possible internal causes.

How can itching be relieved at home?

Moisturizing creams, a cold damp cloth on the itchy area and antihistamines (over the counter) can relieve itching. Avoid hot showers, harsh soaps and synthetic clothing. Scratching worsens itching in the long term.

Can itching be an allergic reaction?

Yes. An allergic reaction to a food, medicine or environmental allergen can cause itching, hives or a more widespread skin reaction. An anaphylactic reaction can begin with itching and requires immediate first aid. Allergy tests help identify the allergen.
