Why am I suddenly have a severe allergic sensitivity after my regular run?

I've ran for over 10 years and directly after one of my runs, as I cooled down, I had a severe allergic reaction (face swelled, tongue swelled, hives) and have to call 911. I thought it was just a fluke, until I two days following I did my same run, and began blowing up again! (Had Benadryl & Prednisone so didn't go to hospital). Any ideas (because the ER doctors be no help) !?
Answers:    Exercise-induced anaphylaxis (EIA), like anaphylaxis itself, is a multi-systemic allergic reaction, meaning that the allergy manifest itself through a spectrum of symptoms affecting the cardiovascular, respiratory, gastrointestinal, or other vital systems. A unique problem, EIA has no nouns to other exercise-related disorders, such as exercise-induced asthma. Source(s): http://runningtimes.com/Print.aspx?artic…
