Skin itching

Overview

Skin itching, also called pruritus, is an uncomfortable feeling that makes you want to scratch. It can affect small areas or your whole body.

Yes, skin itching is very common. Most people experience it at some point in their lives.

Anyone can get itchy skin, but it is more common in older adults, people with dry skin, and those with certain skin conditions or allergies.

Symptoms

Common symptoms

• Persistent urge to scratch
• Red, irritated, or dry skin
• Bumps, blisters, or raised patches
• Thickened or scaly skin from repeated scratching

Symptoms in children

• Itching that is worse at night
• Small red bumps that may ooze (common with eczema or insect bites)
• Rash in skin folds (like behind knees or elbows)

Symptoms in older adults

• Dry, thin skin that itches without a visible rash
• Itching on legs, back, or arms
• Worsening of itching in dry air or winter

Causes

Main causes

• Dry skin (very common, especially in older adults)
• Skin conditions like eczema, psoriasis, or hives
• Allergic reactions to foods, plants (e.g., poison ivy), or animals
• Insect bites or stings
• Internal diseases like liver or kidney problems, thyroid disorders, or anaemia
• Nerve disorders such as shingles
• Medications that can cause itching as a side effect
• Pregnancy (especially in the later stages)
• Stress or anxiety can worsen itching

Risk factors

• Having dry skin or a family history of eczema or allergies
• Being over 65 years old
• Living in a dry climate or during winter months
• Having an underlying medical condition like diabetes, kidney disease, or liver disease
• Taking certain medications
• Having a metal allergy or contact dermatitis

When to see a doctor

See a doctor urgently if:

• If you have itching with a high fever and feel very unwell
• If you have itching all over your body that started suddenly and you have difficulty breathing or swallowing
• If you have jaundice (yellow skin or eyes)
• If you have unexplained weight loss, fatigue, or night sweats

Book a routine appointment if:

• If the itching lasts more than 2 weeks and is not improving
• If it interferes with your sleep or daily life
• If you have a rash that is not going away
• If you have itching without a clear cause
• If you are pregnant and have intense itching, especially on the palms and soles

Diagnosis

Your doctor will ask about your symptoms, medical history, and any recent triggers. They will examine your skin and may ask about your lifestyle, medications, and family history.

Tests that may be done

• Skin exam by your doctor
• Allergy tests (skin prick or blood tests) if an allergy is suspected
• Blood tests to check for underlying conditions like liver, kidney, or thyroid problems
• Skin scraping or biopsy if a skin infection or condition like scabies is suspected

What to expect at your appointment

Your doctor will try to find the cause of your itching. They may recommend simple treatments first. If needed, they will refer you to a skin specialist (dermatologist) or other specialist.

Treatment

Treatment depends on the cause. Many cases can be managed at home. Your doctor may recommend over-the-counter creams or lotions, or prescribe stronger treatments if needed.

Self-care at home

• Moisturise your skin daily with a fragrance-free moisturiser
• Take cool or lukewarm baths with colloidal oatmeal or baking soda
• Avoid perfumed soaps, detergents, and fabric softeners
• Wear loose, soft cotton clothing
• Use a humidifier to add moisture to dry indoor air
• Avoid scratching – keep nails short and consider wearing gloves at night
• Apply cold compresses or ice packs wrapped in a cloth to itchy areas

Medical treatments

Your doctor may suggest topical treatments such as anti-itch creams, ointments, or lotions. They may also prescribe oral antihistamines for allergy-related itching, or other medications to treat underlying causes like eczema or psoriasis. In some cases, creams containing mild steroids may be used for short periods. Always follow your doctor's advice.

When is surgery considered?

Surgery is not usually needed for skin itching itself. If itching is caused by a tumour or other growth, surgery might be considered to treat the underlying problem.

Living with this condition

Living with itchy skin can be frustrating, but simple changes can help. Keep your skin moisturised, avoid triggers, and find ways to distract yourself from scratching. Establish a good skin care routine and stick to it.

Lifestyle tips

• Use gentle, fragrance-free skin products
• Avoid hot showers or baths – use lukewarm water
• Pat your skin dry instead of rubbing
• Wear soft, breathable fabrics like cotton
• Manage stress through relaxation techniques or talking to someone
• Get enough sleep and try to reduce scratching at night

Diet and exercise

There is no specific diet for itching unless an allergy is identified. A healthy, balanced diet supports overall skin health. Stay hydrated and avoid known food allergens. Exercise can improve circulation and reduce stress, which may help some types of itching.

Mental health and emotional wellbeing

Chronic itching can affect your mood, sleep, and quality of life. It can cause irritability, anxiety, and depression. It is important to talk to your doctor if it is affecting your mental health. They can offer support and treatments.

Prevention

Not all itching can be prevented, but you can reduce your risk by keeping your skin moisturised, avoiding known irritants, and managing underlying health conditions.

Vaccines

Vaccines are not specifically used to prevent itching. However, staying up to date with vaccinations can prevent some illnesses that may cause itching, such as chickenpox or shingles.

Screening programmes

No routine screening is recommended for itching. But if you have a family history of skin diseases or relevant conditions, your doctor may suggest regular check-ups.

Complications

If left untreated

• Scratching can break the skin and lead to infections (impetigo or cellulitis)
• Chronic scratching can cause thickened, discoloured skin (lichenification)
• Sleep disturbances and fatigue from nighttime itching
• Emotional distress, anxiety, or depression

Long-term outlook

For most people, skin itching gets better with proper care. If the cause is something like dry skin or an allergy, it often resolves quickly once the trigger is removed. If itching is due to an underlying medical condition, treating that condition usually relieves the itch. Your doctor can help guide you to the right treatment, and most cases can be managed well.
