Itch

(Allergy, Baby-Skin problems, Pruritus, Skin problems)

Also see Allergy

The condition is common but often harmless. However, there may be a serious underlying disorder (e.g., eczema, diabetes, kidney disease).

Symptoms

• Irritating, tickling sensation that makes you want to scratch.

Complications

• Bacterial infection, if scratching causes the skin to break.
• Loss of sleep.
• Irritability.

Common causes
Itch all over:

• Bathing too often, which removes natural oils and leaves the skin dry.
• Allergy (see Eczema, Urticaria).
• Insect bites or stings.
• Certain medicines (e.g., antibiotics)

Itch at particular places only:

• Scalp: Dandruff (see Dandruff), head lice (see Head Lice), ringworm or dry scalp.
• Hands, in between toes, body creases, genitals: Scabies (see Scabies), fungal infections (see Fungal Infection), ringworm (See ringworm)
• Vulva: Thrush (see Thrush), dryness, low hormones due to menopause.
• Anus: Hemorrhoids (see Hemorrhoids), thrush (see Thrush), threadwords (see Worm Infestation).
• Feet: Athlete's foot (see Athletes's Foot).

What you can do

• Bathe or shower regularly to keep yourself free from skin disease, but do not overdo it. Too much bathing can cause the skin to dry and trigger itching.
• Apply calamine lotion or anti-itch cream. Avoid scratching, as the skin may break and get infected. If the itch is unbearable, stroke the itchy area with the finger pads, not the nails.
• Apply an ice pack (ice cubes wrapped in a towel) because heat worsens the itch.
• Take antihistamines (anti-allergy medicine). Do not drive a car or operate heavy machines while on antihistamines, since this medicine can make you drowsy.
• Consult a doctor if you suspect a serious underlying cause, or symptoms persist despite of home treatment.

What your doctor can do for you

• Determine the cause of the itch and treat it.
• Prescribe stronger antihistamines.
• Treat complications.
