Living with hives

Overview

Hives, also known as urticaria, are raised, itchy bumps on the skin that can appear suddenly and then fade. They happen when your immune system releases chemicals like histamine, causing small blood vessels to leak fluid into the skin.

Yes. Around 1 in 5 people will have hives at some point in their life. They are especially common in children.

Hives can affect anyone of any age, gender, or background. They are slightly more common in children and in people with allergies, asthma, or eczema.

Symptoms

Common symptoms

• Raised, red or skin-colored welts that itch, sting, or burn
• Welts that can change shape, join together, or move to different parts of the body
• Swelling around the welts that usually fades within 24 hours
• Worse itching at night, which can disturb sleep

Symptoms in children

• Children often get widespread hives that may look worse than they feel
• Younger children may be fussy, clingy, or show a tummy upset along with the rash
• Hives from viral infections are very common in childhood

Symptoms in older adults

• Hives in older adults can last longer and may be linked to a medical condition, such as a thyroid problem
• The itching can be more intense and may lead to skin infections if scratched
• Older skin may take longer to heal after a hive fades

Causes

Main causes

• Foods — most often peanuts, tree nuts, eggs, shellfish, or milk
• Medicines — such as certain antibiotics and pain relievers (but any medicine could be a trigger)
• Infections — colds and other viral illnesses
• Physical triggers — pressure, heat, cold, sunlight, and sweating
• Stress or emotional upset

Risk factors

• A personal history of allergies, asthma, or eczema
• A recent infection or illness
• Taking a new medication
• Being exposed to a known trigger in large amounts

When to see a doctor

See a doctor urgently if:

• If hives keep coming back for more than a few days and over-the-counter care isn't helping
• If you also have joint pain, fever, or nausea
• If you've just had a vaccine or started new medication and then break out in hives (call the same day)

Book a routine appointment if:

• If hives regularly disrupt your sleep or daily life
• If you notice a clear pattern — for example, hives only after certain foods or activities
• If you have had hives for six weeks or more (chronic hives) so a healthcare professional can help you manage them

Diagnosis

A healthcare professional will listen to your story, ask about possible triggers, and look at your skin. Often that's enough to make a diagnosis.

Tests that may be done

• Allergy tests (like skin prick or blood tests) if a food or medicine trigger is suspected
• Blood tests to check for underlying conditions if hives last a long time
• A small skin biopsy (taking a tiny sample of skin) only in rare cases where the diagnosis is unclear

What to expect at your appointment

Your doctor may ask you to keep a symptom diary that tracks when hives appear, what you ate, what you touched, and how stressed you felt. This information can be very helpful.

Treatment

The main goals of treatment are to calm the itch and help you stay comfortable. For many people, hives disappear within a few days without any treatment. If treatment is needed, the approach depends on how bad the hives are and what's causing them.

Self-care at home

• Apply a cool, damp cloth or take a lukewarm bath to soothe the itching
• Wear loose, soft, cotton clothing to avoid extra irritation
• Avoid scratching — keep nails short and consider tapping the skin lightly instead
• Use unscented lotions or emollients to keep skin calm
• Avoid known triggers such as hot showers, sweating, and tight clothing

Medical treatments

For most cases, a healthcare professional may recommend an antihistamine tablet, which you can take daily. For more severe or chronic hives, a specialist might prescribe stronger treatments, such as steroid tablets used for a short time, or injectable biologic medicines that are given by a doctor. Always ask your doctor or pharmacist about the right treatment and dosage for you.

Living with this condition

Living with hives can feel frustrating, but most people can keep their hives under control with a few simple routines. Track your outbreaks, learn your triggers, and give yourself permission to rest when your skin is reacting.

Lifestyle tips

• Practice relaxation techniques like deep breathing or mindfulness to lower stress
• Stick to a gentle skincare routine with lukewarm water and mild, fragrance-free washes
• Keep a notebook or phone app to record flare-ups and possible triggers
• Let family, friends, and colleagues know about your hives and how they affect you

Diet and exercise

There's no one-size-fits-all diet for hives. Unless an allergy is confirmed, avoid cutting out any foods without a professional's advice. Gentle exercise is good for general health, but sweating can trigger hives in some people, so keep activities cool and stay in an air-conditioned or breezy space if needed.

Mental health and emotional wellbeing

Living with itchy, unpredictable hives can be wearing. It's normal to feel anxious, frustrated, or embarrassed, especially if your skin bothers you in public. These feelings are common and worth talking about with your doctor or a counsellor.

Prevention

If you know what triggers your hives, avoiding those triggers is the best way to prevent them. If your hives are linked to stress, managing stress levels may reduce flare-ups.

Vaccines

There is no vaccine for hives. However, getting recommended vaccinations for infections you're exposed to may help prevent some illnesses that can trigger hives.

Screening programmes

There is no routine screening for hives. If you have a family history of allergies or an autoimmune condition, your healthcare professional may suggest extra monitoring when symptoms appear.

Complications

If left untreated

• Most hives don't cause serious problems. But if a severe allergic reaction starts, it needs emergency care
• Untreated chronic hives can greatly affect sleep, work, and quality of life
• Scratching a lot can damage the skin and lead to infections

Long-term outlook

The outlook for hives is very good. Acute hives usually settle within days. Even chronic hives can often be brought under good control with the right support. Most people with hives are healthy and live full, active lives.
