Definition: Hives, also known as urticaria, are raised, itchy welts that appear on the skin. They can be red, pink, or skin-colored and vary in size and shape. Hives can appear suddenly and disappear within hours or last for days or weeks.
Causes: Hives can be triggered by various factors, including allergies (food, medication, insect bites), infections, autoimmune diseases, and physical factors (pressure, friction, sun). In many cases, the cause is unknown.
Pros of Treatment: Treatment can relieve itching and improve appearance.
Cons of Treatment: Antihistamines (common treatment) can cause drowsiness or other side effects. Topical steroids may be used for short periods but have potential side effects with long-term use.
Alternatives: Identifying and avoiding triggers is key. Cooling the skin with compresses or calamine lotion may provide relief.
Recovery Time: Acute hives (less than 6 weeks) typically resolve on their own or with treatment within days. Chronic hives (lasting longer) require further evaluation and treatment.
Disclaimer: If hives are severe, widespread, or accompanied by trouble breathing, seek immediate medical attention.
