"Giant urticaria" isn't a medical term commonly used. However, "giant hives" or "giant urticaria" may refer to severe cases of urticaria, also known as hives. Urticaria is a skin condition characterized by raised, itchy welts (wheals) that can range in size from small spots to large patches. Here's a breakdown of symptoms, treatment plans, and diagnosis/testing for urticaria.

1. Raised Welts: Large, raised welts or hives on the skin. These may vary in size and shape and may merge together to form larger patches.
2. Itching: Intense itching or burning sensation in the affected areas.
3. Redness: The skin around the welts may appear red or inflamed.
4. Swelling: Swelling may occur in the affected area, particularly if the hives are large.
5. Warmth: The skin may feel warm to the touch in the affected areas.
6. Pain: In some cases, hives may be accompanied by mild pain or discomfort.

1. Antihistamines: Oral antihistamines, such as cetirizine, loratadine, or fexofenadine, are usually the first-line treatment for urticaria. They help relieve itching and reduce the appearance of hives.
2. Corticosteroids: In severe cases or when antihistamines alone are ineffective, short courses of oral corticosteroids may be prescribed to reduce inflammation and control symptoms.
3. Topical Treatments: Calamine lotion or over-the-counter hydrocortisone cream may be applied topically to soothe itching and reduce inflammation.
4. Avoid Triggers: Identifying and avoiding triggers, such as certain foods, medications, or environmental factors, can help prevent recurrence of hives.
5. Cool Compresses: Applying cool compresses or taking cool baths can provide relief from itching and help reduce swelling.
6. Immunomodulators: In some cases of chronic hives that do not respond to conventional treatment, immunomodulatory medications such as omalizumab may be prescribed to help regulate the immune response.

1. Medical History: A healthcare provider will typically take a detailed medical history to assess the duration, frequency, and triggers of the hives.
2. Physical Examination: A physical examination of the skin is performed to observe the appearance and distribution of the hives.
3. Allergy Testing (if indicated): Allergy testing may be recommended if there is suspicion of an allergic trigger for the hives.
4. Blood Tests (if indicated): Blood tests, such as a complete blood count (CBC) or tests for specific antibodies, may be ordered to help identify underlying causes of chronic hives, such as autoimmune conditions or infections.
