Urticaria

Urticaria, or hives, is a skin reaction characterized by itchy, raised welts that can appear on large or small areas of the skin. These welts may be reddish or skin-colored and often appear suddenly in response to triggers like infections, certain foods, allergies, or medications. The rash typically resolves on its own, but if it persists, medication may be required.

Symptoms of Urticaria

Symptoms of urticaria can change rapidly, and the rash may shift in shape and location on the skin. Itching often begins before the rash becomes visible and may feel intense. Common symptoms include raised, reddish or skin-colored welts that may appear translucent in the center. Hives frequently occur on the upper body, arms, and legs. Typically, urticaria fade within a few days, with the skin returning to normal.

Causes of Urticaria

Urticaria can be triggered by various factors, such as allergens, environmental irritants, or stress.

Common causes include:

• Infections, like respiratory tract infections
• Psychological factors, such as stress and anxiety
• Medications, like antibiotics or anti-inflammatory drugs
• Physical irritants, like heat, cold, and pressure
• Food items, such as nuts, fish, eggs, shellfish, and dairy products

Treatment and Self-care

Most cases of urticaria resolve on their own without special treatment. Antihistamine medication can help alleviate itching. If symptoms persist or are severe, a doctor may prescribe stronger medications and creams.

Self-care tips:

• Use antihistamines to relieve itching
• Avoid skin irritants, such as excessive heat, cold, and heavy sweating
• Try mild corticosteroid cream treatment for localized itch relief

When to seek medical care?

Contact a doctor if urticaria does not clear up within two weeks or if it recurs. Seek immediate medical care if the rash spreads quickly and is accompanied by facial swelling or difficulty breathing.
