Why do my allergies react like this??

Question:

I am allergic to cats, this i am already aware of, but my cat allergies don't react like normal animal allergies, you know the stuffy or runny nose, swollen eyes, slight fever, that don't happen to me, my tongue swells up. Really as if i have eaten something that i am allergic to rather than just been in a room with them. It isn't as funny as it sounds. My face turns red, i get a fever, my nose swells, my throat (not so much as i can't breathe, it is just much harder), and my eyes swell. Then my chin and throat start itching, and my ears. and i brake out in a kind of hives, and then my eczema gets crazy, and itches, i just turn into a mess. The first time it happened i was truly scared. My parents took me to my doctor, and the first thing out her mouth was "were you tasting the cat?" but as far as an answer, she didn't have one, she just game me some antihistimenes and antibiotics. I wanna kno, does this happen to anyone else, is it normal, can i fix it?

Answers:
that sounds like a pretty severe histamine reaction. they call it anaphylactic shock. normally, it only happens to those that are allergic to bees, and certain types of food, like peanuts. it causes your airways to constrict, and your histamine levels go up to the point that your blood vessels swell up to the point of constricting your airway. generally, they give you a shot of epinephrine or adrenaline, which counteracts the histamine.

I take this injection that I keep with me at all times. If it happens then i just the shot in my arms or neck. They told me to keep Cats off my menu.
