Fachad,

First I just want to say that you are VERY special - not only are you a fountain of knowledge, but you are kind, thoughtful and just plain nice in your willingness to share. I greatly appreciate it all.

Okay, moving along to the ol' histamine receptors, I have a question about something you explained. You wrote: "An allergen in the body is perceived as an irritant, histamine is released, histamine receptors are activated, nerve impulses are transmitted, and the final event is hives or whatever."

What do you mean by "HISTAMINE RECEPTORS ARE ACTIVATED" - I am under the impression (Probably wrong!) that the histamine receptors would be holding tanks, so to speak, for histamine? In other words, once the body releases histamine (in response to the allergen) is that histamine then kept, for lack of a better word, in the histamine receptors? If so, the blocking the receptors prevents them from eventually letting go of the histamine and prevents the allergic reaction?

I have a feeling I'm still missing a piece of the puzzle when it comes to RECEPTORS! Argh ...
