I think I am sicker than I have ever been in my entire life. I went into work this morning and only lasted 3 hours. I feel like puking non-stop, I have ZERO energy/strength, my entire body hurts all over. Now my head is pounding, throat is swollen nearly shut, and it's freaking cold everywhere I go! Anybody know what I might have? I thought it was allergies/sinuses, but they don't do this to me.
