allergies or Flu like symptoms?

[Bellababy09]

First off i feel like Crap
2 days ago i started feeling crappy first my head was hurting then i had running nose and i just couldn't stop sneezing yesterday it was the same thing but all of a sudden i got slight case of hives on my neck and insides of my arm . i put cold water on them because i didn't have benedryl at work. it got a little better i still felt disgusting. when i got home i was doing okay and then again i got the hives under my lip and around my forehead and upper cheek bones.
I took allegra before i went to bed and slept fine but when i woke up today my throat was hurting and it was really dry.
Iam at work currently and my whole body is in pain and my neck is killing my my eyes keep watering and i can only breath out of one nostril.
is it allergies? or can i be coming down with something.
i ve never suffered from allergies. but i know they can pop up at anytime. Or maybe its my work place too dusty or not enough air circulation?

HELP!!
