Urticaria, commonly known as hives, is a condition that causes raised, itchy welts on the skin. These welts can appear suddenly, change shape, and often come and go within hours.
In clinical practice, urticaria is something we see quite often. It can be short-lived (acute) or persist for weeks to months (chronic urticaria), and the experience can vary significantly between individuals.
While it can be uncomfortable and sometimes distressing, most cases are not dangerous — although identifying triggers and patterns can be important.

Most cases of urticaria are not dangerous, but you should seek urgent care if you experience:
These may indicate a more serious allergic reaction (anaphylaxis) and require immediate medical attention.
Individual hives: Usually resolve within 24 hours
Acute urticaria: Days to weeks
Chronic urticaria: Can persist for months or longer
While chronic urticaria can be persistent, many people experience gradual improvement over time.
Urticaria can be unpredictable, especially when triggers aren’t clear. We often see patients feel frustrated by:
With the right management approach, symptoms can often be controlled effectively.
