That sudden outbreak of itchy, red welts on your skin isn’t just a random annoyance – it’s your body sending you an important message. Hives, medically called urticaria, occur when your immune system sounds a false alarm, causing skin cells to release histamine that leads to those characteristic swollen patches.
What makes hives particularly frustrating is their unpredictable nature. They might appear after eating certain foods, taking medication, or even when you’re stressed. Some people develop them from physical triggers like cold weather, heat, or pressure on the skin. The welts typically last less than a day in one spot but may pop up elsewhere, playing an annoying game of hide-and-seek on your body.
While most cases are temporary, some people experience chronic hives that last for months, often without any obvious cause. In severe cases, the swelling can extend deeper into the skin, especially around sensitive areas like the eyes and mouth. The good news? Simple antihistamines can usually control symptoms, and avoiding known triggers can prevent future outbreaks.
