Typically, hives have well-defined edges and may resemble bug bites, though they tend to appear and disappear more rapidly. The size and shape of hives can vary significantly, ranging from small dots to large patches. Pressing on the center of a hive frequently enough causes it to turn white, a phenomenon known as blanching.
Where Do Hives Appear?
Hives can appear anywhere on the body, either in clusters covering large areas or as isolated welts. Some individuals may experience recurring hives in the same location, often triggered by a specific factor.
When to Seek Medical Attention
While hives are often easily identifiable, certain symptoms warrant immediate medical attention. According to Sapna Palep, MD, founder and medical director at Spring Street Dermatology in New York City, you should call 911 or see a doctor instantly if you experience swelling of the eyes, lips, or throat, or if you have difficulty breathing. These symptoms could indicate anaphylaxis, a severe allergic reaction.
How Long Do Hives Last?
Acute hives usually disappear within 24 hours, although new hives may continue to appear as older ones fade. In total, hives can persist from a few days to several weeks.
Chronic hives, on the other hand, last longer than six weeks and may recur randomly over extended periods.
