As you?ve probably figured out by now, hives is one of those health matters that?s easy to recognize, but difficult to determine what caused it in the first place. An outbreak can occur because it?s in your bloodline, or because you bumped into something you?re allergic to.
The physical manifestation of the hives is caused when blood plasma, in response to the production of histamine, leaks into your skin from small blood vessels. The histamine is released from special cells that are near to those blood vessels.
