Urticaria & Angioedema (Hives and Swelling)
Urticaria (hives) and angioedema (deeper swelling beneath the skin) are reactions that cause sudden red, itchy welts or swelling, commonly affecting the skin, lips, eyes, or hands. Episodes may occur once, recur frequently, or persist for several weeks.
The allergists at The Medical Group of New Jersey specialize in diagnosing and managing these conditions using a personalized approach that identifies triggers and provides long-term symptom control.
Symptom Onset & Initial Evaluation
Hives and swelling can appear suddenly, often following exposure to a trigger such as certain foods, medications, insect stings, environmental allergens, or infections. In some cases, the cause is identifiable, but many times, symptoms occur without a clear trigger.
Common symptoms include:
- Itchy hives or welts that move, fade, or change shape over time
- Sudden swelling of the lips, eyes, hands, or throat
- Symptoms that worsen at night or during periods of stress
Important: Swelling of the throat or tongue can be life-threatening. Call 911 or go to the nearest emergency department immediately if you experience these symptoms.
Diagnosis
Diagnosis of urticaria and angioedema is primarily clinical, based on the appearance, timing, and possible triggers of symptoms. Your allergist will perform a thorough evaluation to determine the underlying cause and identify contributing factors.
Additional testing may include:
- Autoimmune and thyroid antibody testing: Helps detect autoimmune conditions that can contribute to chronic hives and/or swelling.
- Complement studies: Used to diagnose hereditary angioedema, a rare genetic cause of recurrent swelling.
- Trigger testing: Evaluates reactions to physical stimuli such as temperature, pressure, or vibration in cases of physical urticaria.
These tests help your allergist create a personalized treatment plan to manage symptoms effectively and reduce future flare-ups.
Treatment & Ongoing Management
Management focuses on avoiding triggers, controlling symptoms, and preventing recurrences. Our allergy specialists develop personalized care plans that minimize discomfort, reduce flare frequency, and improve overall quality of life.
Treatment options may include:
- Trigger avoidance and stress management: Identifying and avoiding known triggers, such as certain foods, medications, or environmental factors, helps prevent future flare-ups. Managing stress can also reduce symptom frequency.
- Daily non-sedating antihistamines: The foundation of therapy, these medications help relieve itching, hives, and swelling.
- Combination or higher-dose antihistamines: Used for chronic or persistent symptoms when standard doses aren’t sufficient.
- Short courses of corticosteroids: May be prescribed to calm severe or sudden flares.
- Epinephrine auto-injector: Recommended for patients who experience swelling that affects the throat or airway.
- Biologic therapy (omalizumab): An advanced option for patients with chronic or treatment-resistant symptoms, targeting the immune pathway involved in inflammation.
With consistent care and follow-up, most patients experience lasting symptom control and improved comfort.
Prognosis & Follow-Up
With expert care from The Medical Group of New Jersey, most patients experience significant relief and regain confidence in managing their symptoms. Acute hives often resolve within days, while chronic urticaria and angioedema can persist but are typically well-controlled with consistent treatment and follow-up.
Your allergist will schedule regular follow-up visits to monitor progress, adjust therapy as needed, and rule out any underlying conditions. With proactive management and personalized care, patients can maintain comfort, reduce recurrence, and prevent future flare-ups.
