Understanding
Recurrent Hives
Hives, also known as urticaria, are raised, itchy welts that develop on the skin as a result of histamine and other inflammatory chemicals being released. When hives continue to recur over days, weeks or months, they may indicate an underlying allergic, immunological or, less commonly, autoimmune condition.
Understanding how often your hives occur, how long they last and whether they are associated with specific triggers or other symptoms can help determine the underlying cause and guide appropriate treatment.
What Do Recurrent Hives Look and Feel Like?
Each individual outbreak of hives usually develops suddenly and fades within a few hours, often disappearing within 24 hours without leaving scars. However, new hives may continue to appear as older ones resolve, resulting in repeated or persistent outbreaks.
Recurrent hives may present as:
Raised, red or skin-coloured welts
Welts that vary in size and shape
Individual hives that usually disappear within 24 hours without leaving scars
Swelling of the lips, eyelids or deeper tissues (angioedema) in some people
Intense itching
Hives that appear anywhere on the body
Repeated outbreaks over days, weeks or months
Although hives themselves are usually a temporary allergic condition, recurrent episodes may significantly affect sleep, daily activities and quality of life.
What Can Cause Recurrent Hives?
Recurrent hives occur when inflammatory chemicals, particularly histamine, are released into the skin. This process can be triggered by a variety of allergic, immunological and physical factors.
Chronic Spontaneous Urticaria
In many people, recurrent hives occur without an obvious external trigger. This condition, known as chronic spontaneous urticaria, may be associated with immune system dysfunction and can persist for months or longer.
Allergic Reactions
Foods, medications, insect stings and other allergens may trigger episodes of hives. These reactions usually occur soon after exposure to the trigger, although identifying the exact cause is not always straightforward.
Physical Triggers
Some people develop hives in response to physical stimuli such as pressure, heat, cold, exercise, sunlight or sweating. These are known as inducible urticarias.
Autoimmune and Other Medical Conditions
Less commonly, recurrent hives may be associated with autoimmune diseases, infections or other underlying medical conditions. A comprehensive assessment helps determine whether further investigation is required.
When Should Recurrent Hives Be Assessed by a Specialist?
Most episodes of hives are temporary and resolve without long-term problems. However, recurrent or persistent hives may require specialist assessment, particularly when they occur frequently, have no obvious trigger or are accompanied by other symptoms.
Signs that your recurrent hives may need assessment:
Hives that recur for more than 6 weeks
Swelling of the lips, tongue or eyelids (angioedema)
Symptoms that worsen with heat, cold, pressure or exercise
Symptoms suggestive of thyroid disease or other autoimmune conditions
Hives that persist despite antihistamine treatment or continue to interfere with your daily activities
Episodes that occur without an obvious trigger
Hives triggered by specific foods, medications or insect stings
Joint pain, fever or unexplained fatigue
A personal or family history of autoimmune disease or allergic conditions
A comprehensive evaluation can help identify potential triggers, determine whether an underlying allergic, immunological or autoimmune condition is contributing to your symptoms, and guide the most appropriate treatment.
How Do Rheumatologists Diagnose the Cause of Recurring Hives?
Because recurrent hives can have many different causes, diagnosis begins with a detailed assessment of your symptoms, medical history and possible triggers.
Clinical Assessment
Your rheumatologist will ask when your hives first began, how frequently they occur, how long each episode lasts and whether they are associated with foods, medications, infections, exercise or physical triggers such as heat, cold or pressure. They will also ask about angioedema, other allergic symptoms and features that may suggest an underlying autoimmune or immunological condition.
Allergy Testing and Other Investigations
Where appropriate, allergy testing may be recommended to identify possible allergic triggers. Additional investigations may also be considered if an autoimmune or other underlying medical condition is suspected.
Blood Tests
Allergy blood tests may also be recommended to assess for signs of inflammation, thyroid disease, autoimmune conditions or other underlying disorders where clinically indicated. These investigations can also help exclude less common causes of chronic or recurrent hives.
Following your assessment and investigations, your rheumatologist will determine whether your hives are most consistent with chronic spontaneous urticaria, inducible urticaria, an allergic reaction or another underlying condition, allowing an appropriate treatment plan to be developed.
Comprehensive Assessment for
Recurrent Hives with Dr Anindita Santosa
Persistent or recurring hives can be frustrating to live with, particularly when flare-ups occur unpredictably or interfere with your sleep, work or daily activities. Although many cases improve with appropriate treatment, others require a more detailed evaluation to identify potential triggers or determine whether an underlying medical condition is contributing to the symptoms.
At Aaria Rheumatology, patients receive personalised assessment and care for recurrent hives and other allergic conditions. As an allergist, Dr Anindita Santosa evaluates your symptoms, potential triggers and relevant test results to identify possible causes and develop an individualised management plan.
If hives keep returning, have no clear trigger or are affecting your daily life, book an appointment with Dr Anin for a comprehensive assessment.
