In some cases, such reactions may also be triggered by exercise or running (2). Mary, a blogger, found herself in a desperate attempt to outrun an encroaching allergic reaction in the midst of a seemingly routine run. She explained in her blog, “I have a condition called Exercise-Induced Anaphylaxis, or EIA…after an easy 60-minute run, experiencing anaphylactic shock where my face blew up like a balloon and my throat started closing up. I occasionally develop hives or moderate facial swelling after a tough workout (i).” Despite occasional ER visits, she remains resolute in her fitness goals, proving that these setbacks won’t hinder her drive.
