Re: My Sweat Creates Poison Ivy Like Rash

I don't think you are allergic to your own sweat, rather, you have exercise or heat induced uticaria (hives).

Definitely, it'll help to avoid becoming overheated. Have you tried a daily antihistamine? It works better as a preventative than as a cure after the fact. Many people find that Zyrtec is the most effective antihistamine for hives and rashes.

Also, is it possible you are sensitive to certain laundry detergents or fabric softeners?
