In brief: Acute allergy.

There are actually different types like the delayed ones.
The common ones are the acute allergic reaction. You have allergy cells (eosinophils, basophils, mast) with receptors on the surface. The allergen (the cause) binds to those receptors, the cells lyse, recruit other cells, but the contents cause the blood vessels and surrounding tissue to react and cause the wheal and flare reaction.
