Chronic Hives (Chronic Idiopathic Urticaria)
Chronic hives, or chronic idiopathic urticaria, are red, itchy welts on the skin that persist for over six weeks, often appearing at least twice weekly. These welts, also known as wheals, may last for months or years, and their cause is frequently unknown. People with autoimmune conditions are more likely to develop chronic hives. Treatments like antihistamines, steroids, or immunosuppressants can help manage symptoms.
Hives involve raised, red skin patches, while angioedema causes deeper tissue swelling, potentially affecting the face, lips, throat, hands, feet, or genitals. Unlike acute hives, which fade within 24 hours and resolve within six weeks (often triggered by a recent viral infection), chronic hives persist longer and lack a clear cause.
