College soccer player allergic to her own sweat

An Ohio college soccer player had to overcome a strange malady to keep playing - being allergic to her own sweat.

Caitlin McComish has had food allergies since she was a child. While out on a run last May, she started to feel sick. Her throat began to close up, and she had trouble breathing. She managed to call her mother before collapsing.

After going to the hospital, McComish was diagnosed with cholinergic urticaria, a hives disorder that's triggered by sweat.

A study published in the Journal of the American Academy of Dermatology suggests it affects more than 11 percent of the population, although the majority showed only mild symptoms.

As you can imagine, sweat and soccer go hand in hand - the University of Toledo goalie suffered 17 attacks that summer alone. So how does McComish still play without breaking out in hives every time?

Her doctor tried several treatments, such as antihistamines, wearing a cooling vest, ice baths before and after practice, but ABC says none of those worked.

He finally started giving her injections of Xolair, a drug normally used as a treatment for asthma. The drug made a dramatic difference, not only letting McComish play soccer, but also clearing up some of her food allergies.

McComish has been medically disqualified from playing this year due to a different disorder. She says these experiences made her realize her health comes first.
