Urticaria (hives)
Urticaria, commonly known as hives, is a skin condition characterized by red, itchy welts that can appear suddenly on any part of the body. These welts vary in size and can form in patches or spread to larger areas. The underlying cause is often linked to an allergic reaction to food, medication, insect bites, or even environmental factors like pollen and temperature changes. However, in some cases, the exact cause remains unknown.
The welts caused by urticaria can last from a few hours to several days and may come and go unpredictably. They result from the release of histamines and other chemicals in the skin, leading to swelling and itching. While hives can be uncomfortable, they are usually harmless and often resolve without treatment.
For relief, many individuals use antihistamines to manage symptoms and reduce itching. It's also important to identify and avoid potential triggers to prevent future outbreaks. In severe cases, medical attention may be necessary to control symptoms and investigate underlying causes.
