Overview
Chronic urticaria is a skin condition that causes raised, itchy hives to appear on your body for more than six weeks. These welts can show up anywhere on your skin and often move around to different areas throughout the day.
About 1% of people worldwide live with chronic urticaria. It affects women twice as often as men and typically develops between ages 20 and 40. The condition can be frustrating because the hives seem to appear without warning.
Unlike acute urticaria that clears up quickly, chronic urticaria persists and can significantly impact your daily life. Understanding this condition helps you work with healthcare providers to find effective treatment options and manage symptoms better. The hives usually appear as raised bumps that are very itchy and uncomfortable. They may come and go throughout the day, making it hard to predict when you'll feel relief.
Symptoms & Signs
Chronic urticaria symptoms can vary from person to person, but certain patterns help identify the condition.
Primary Symptoms
Raised welts (hives) that appear red or pink on light skin and may be less visible on darker skin
Intense itching that often gets worse at night or with stress
Swelling (angioedema) around eyes, lips, hands, feet, or genitals
Hives that change location throughout the day, appearing in new areas while others fade
When to Seek Care
Watch for signs that indicate you need medical attention. Difficulty breathing, swallowing problems, or rapid spread of hives requires immediate care. Persistent symptoms lasting more than six weeks also need professional evaluation. If your hives are making it hard to sleep or affecting your school or work, talk to a doctor right away. Some people also notice their hives get much worse during certain times of the year or season.
When to Seek Immediate Care
Call emergency services if you experience difficulty breathing, severe swelling of face or throat, or feel dizzy and weak along with hives.
Causes & Risk Factors
The exact cause of chronic urticaria remains unknown in about 80% of cases. However, researchers have identified several potential triggers and contributing factors.

Most common between ages 20-40, though can occur at any age
Genetics
Family history of allergies or autoimmune conditions increases risk
Lifestyle

Diagnosis
Medical History & Physical Examination
Your doctor will ask detailed questions about when your hives started, what they look like, and potential triggers. They'll want to know about any medications you take, foods you eat, and stressful events in your life. A physical examination helps them see the hives and check for other signs of allergic reactions.
The doctor will also ask about family history of allergies or autoimmune conditions. They may have you keep a symptom diary to track when hives appear and what might trigger them. This information helps identify patterns and possible causes.
Diagnostic Testing
Allergy tests to identify specific triggers like foods, medications, or environmental allergens
Blood tests to check for underlying conditions like thyroid disorders or infections
Skin biopsy in rare cases to rule out other skin conditions that mimic urticaria
Treatment Options
Treatment focuses on controlling symptoms and preventing flare-ups while identifying and avoiding triggers when possible.
Conservative Treatments
Antihistamines work as first-line treatment to reduce itching and prevent new hives from forming
Stress management techniques like meditation, yoga, or counseling help reduce stress-related flare-ups
Cool compresses applied to affected areas provide temporary relief from itching and inflammation
Advanced Treatments
Immunosuppressive medications like cyclosporine may be prescribed when antihistamines don't work effectively
Biologic medications such as omalizumab help people with severe chronic urticaria that doesn't respond to other treatments
Corticosteroids might be used short-term for severe flare-ups, but aren't suitable for long-term use
Your doctor will work with you to find the best treatment plan for your specific situation. Treatment may need to be adjusted over time as your symptoms change. Many people need to try several different approaches before finding what works best for them.
Living with the Condition
Daily Management Strategies
Keep a detailed diary of your symptoms, potential triggers, and what helps provide relief. This information becomes valuable when working with your healthcare team. Take antihistamines as prescribed, even on days when you don't have symptoms, as they work better for prevention than treatment.
Wear loose-fitting, soft clothing made from natural fibers to reduce skin irritation. Avoid hot showers or baths, as heat can worsen itching and trigger new hives. Keep your living space cool and use gentle, fragrance-free soaps and moisturizers.
Create a stress management routine that works for your lifestyle. This might include regular exercise, meditation, adequate sleep, or counseling for chronic conditions. Managing stress effectively often reduces the frequency and severity of hive outbreaks. Talk with friends and family about your condition so they understand what you're going through. Having support from people around you makes managing chronic urticaria easier.
Exercise & Movement
Gentle exercise like walking, swimming in cool water, or yoga can help manage stress without triggering hives. Avoid intense workouts that cause excessive sweating or overheating, as these can trigger symptoms. Choose exercise times when your symptoms are typically better, and always have antihistamines available. Starting with short activities and slowly building up helps you find what your body can handle. Exercising in the morning or evening when it's cooler may work better than exercising during hot times of day.
Prevention
Identify and avoid your personal triggers through careful tracking and elimination diets when appropriate
Manage stress through regular relaxation techniques, adequate sleep, and healthy coping strategies
Take prescribed antihistamines consistently, even during symptom-free periods
Maintain a cool environment and avoid rapid temperature changes that might trigger hives
Use gentle, fragrance-free personal care products and avoid known irritants
Keep emergency medications available if you've experienced severe reactions in the past
