hives that comes and goes

Overview

Hives, also called urticaria, are raised, red or pink bumps on the skin that often itch. They can appear suddenly, fade, and then come back — sometimes within hours or days. This pattern is called recurring hives.

Yes. Hives are very common. Around 1 in 5 people will have hives at least once in their lifetime.

Anyone can get hives, but they are more often seen in children. Women are affected more frequently than men. People with allergies, asthma, or a family history of hives are at higher risk.

Symptoms

Common symptoms

• Raised, red or pink welts on the skin that may be small or large
• Intense itching, and sometimes a burning or stinging feeling
• Welts that appear and fade within a few hours, while new ones may appear elsewhere
• A feeling that the spots move around or change shape

Symptoms in children

• Hives often appear after a common infection, like a cold or stomach bug
• Children may be fussy and scratch a lot, which can make the skin look worse
• Welts may come and go quickly, sometimes over a few hours

Symptoms in older adults

• Hives may be less itchy but can last longer
• Older skin can bruise or tear more easily from scratching
• Taking a new medicine may be the cause – always check with a doctor or pharmacist

Causes

Main causes

• An allergic reaction to a food, such as nuts, eggs, or shellfish
• An allergic reaction to a medicine, such as certain antibiotics or pain relievers
• An infection, including a cold or flu-like illness
• Physical triggers such as heat, cold, sunlight, pressure, or exercise
• Stress and strong emotions
• No identifiable cause in many cases (doctors call this chronic spontaneous urticaria)

Risk factors

• A personal or family history of allergies, asthma, or eczema
• Having an autoimmune condition, such as thyroid disease
• Recent use of new medicines or contact with harsh chemicals
• Being a woman – hives are reported more often in women

When to see a doctor

See a doctor urgently if:

• If you have symptoms from the emergency list (trouble breathing, throat swelling, dizziness), call your local emergency number immediately.
• If hives appear after taking a new medicine and you feel unwell, seek medical advice the same day.
• If hives are very painful, or are accompanied by fever or joint pain, see a doctor urgently.

Book a routine appointment if:

• If your hives keep coming back and do not improve within a couple of weeks.
• If hives disrupt your sleep, work, or daily life.
• If you would like help identifying what is causing them.

Diagnosis

A doctor usually diagnoses hives by looking at your skin and asking about your symptoms. They will want to know when the hives started, how long each welt lasts, and whether you noticed any triggers such as foods, medicines, or physical activity.

Tests that may be done

• A symptom diary – you write down when hives appear and what you ate, touched, or did that day
• Allergy tests, such as a skin prick test or a blood test, if a specific trigger is suspected
• Blood tests to rule out other conditions if hives persist for weeks
• Physical tests – for example, applying a little heat, cold, or pressure to the skin to see if it triggers a welt

What to expect at your appointment

Most people do not need testing straight away. Your doctor will likely start with simple questions and a physical examination. If hives continue for more than six weeks or the pattern is unusual, more tests may be arranged.

Treatment

Treatment focuses on controlling symptoms while your body recovers. The best approach is to identify and avoid what triggers your hives. Medication can help reduce itching and swelling, especially during an outbreak.

Self-care at home

• Apply a cool, damp cloth to calm itchy areas
• Take a cool (not cold) bath or shower to soothe the skin
• Wear loose, soft cotton clothing
• Use a plain, fragrance-free moisturiser to protect the skin
• Avoid hot showers, tight clothing, and heavy sweating
• Do not scratch – use a cold pack or ask your pharmacist about soothing creams

Medical treatments

Your doctor may suggest a type of medicine called an antihistamine. This helps block the chemical in the body that causes hives. It is important to take the right dose for your age and situation, so always ask your doctor or pharmacist for advice. For stubborn hives, a specialist may recommend other non-drug treatments or prescription medicines.

Living with this condition

Living with recurring hives means learning to read your skin's signals. Keep a simple diary – note when hives appear, what you ate, where you were, and how stressed you felt. Over time, you may see a pattern.

Lifestyle tips

• Stay cool and avoid sudden temperature changes
• Manage stress with breathing exercises, mindfulness, or talking things through
• Choose gentle, unscented soaps, detergents, and cosmetics
• Wash new clothes before wearing them to remove possible irritants

Diet and exercise

A balanced diet keeps your immune system healthy. If you think a food triggers your hives, talk to a doctor or dietitian before cutting out whole food groups. Regular exercise is good for you, but if you notice hives after exercise, mention it to your doctor – there are ways to manage this.

Mental health and emotional wellbeing

Hives can be frustrating and sometimes embarrassing. The constant itching and unpredictability can affect sleep and mood. It is completely normal to feel anxious or down when your skin is not behaving.

Prevention

If you know your triggers, you can often reduce the chance of an outbreak. For example, avoiding certain foods, keeping cool, or learning to manage stress. However, not all hives can be prevented, and that is not your fault.

Complications

If left untreated

• In rare cases, hives can cause deep swelling under the skin, called angioedema, which may affect the face, lips, or throat and can be dangerous.
• Scratching can damage the skin and lead to an infection.
• Ongoing hives can affect your sleep, work, and quality of life.

Long-term outlook

The outlook is very good. Most hives clear up within a few days. Even when hives keep coming back for weeks or months, they often settle down over time. With the right treatment and support, the majority of people manage their symptoms well.
