Hives are also known by the name of urticaria, welts, nettle rash and wheals. They are a common cause of skin inflammation. Hives are red, raised and itchy rashes that often get instigated by something producing an allergic reaction- an allergen. When we find any allergic reaction, the body tends to release a protein named histamine.
When histamine is released the capillary leaks fluid, that accumulates in the skin and leads to a rash. The rash can appear on only one part of the body or across larger areas. If the affected area changes its color in 24 hours and the rash gets better in a few days or clears up in six weeks then it is termed as acute urticaria.
When the rash develops and come and go for more than six weeks, then this is chronic urticaria. The reaction due to allergies can be one of the causes of hives, but there are other causes of hives too.
