Hives or Urticaria

Hives, also known as urticaria, are a common skin condition characterized by raised, red, and itchy welts or wheals on the skin. They can vary in size and shape and may appear and disappear rapidly. Hives are typically an allergic reaction, and they can occur anywhere on the body.

Key features of hives (urticaria) include:

1. Raised Welts: The welts or wheals associated with hives are typically raised above the surrounding skin. They can be round, oval, or irregular in shape.

2. Red or Pink Color: Hives often have a red or pink color, and the skin surrounding the welts may appear normal.

3. Itching: One of the hallmark symptoms of hives is itching, which can be mild to severe. Itching may be the first symptom before the appearance of welts.

4. Rapid Onset and Resolution: Hives can appear suddenly and may disappear within hours or days. In some cases, new hives may develop as old ones fade.

5. Change in Size and Shape: Hives can change in size and shape rapidly, and they may merge to form larger areas of raised skin.

6. Triggers: Hives can be triggered by various factors, including allergens (foods, medications, insect stings), infections, stress, and physical stimuli (such as pressure, cold, or heat).

7. Angioedema: In some cases, hives may be accompanied by angioedema, which involves swelling in the deeper layers of the skin, often around the eyes, lips, or other areas. Angioedema can cause a more pronounced and deeper swelling.

If hives are accompanied by symptoms such as difficulty breathing, swelling of the face or throat, or other signs of a severe allergic reaction (anaphylaxis), it is a medical emergency, and immediate medical attention is required.

Management and treatment of hives typically involve identifying and avoiding triggers, if possible. Antihistamines are commonly used to relieve itching and reduce the severity of hives.
