Hives are itchy, pink swellings that can vary in size and cause burning and stinging. The most common causes of hives are foods, drugs, infections, warming of the skin after exposure to the cold, sweating, sunlight, hot baths, blushing, or anger. They are very common and usually go away within a few days to few weeks, however early treatment can alleviate discomfort and complications.
Antihistamines are usually prescribed to treat hives. No one antihistamine works for everyone so your dermatologist may have to try more than one or different combinations to find what works for you.
