A skin rash is any sort of skin inflammation. The normal skin color or texture will change and the skin becomes scaly, bumpy, or itchy.

Urticaria, otherwise commonly known as hives, is characterized by raised and erythematous wheals that develop because of the release of vasoactive substances, especially histamine from mast cells.

Urticaria can be triggered by many mechanisms, which are divided into allergic and nonallergic. However, in about one-half of urticaria cases, the triggering factor cannot be identified.
