Urticaria -- definitely not the cats... but possibly fabric???

[Guest guest]

Well, I went to the allergist today to just get tested for cat

allergy and I am not allergic to them at all. Last night though, I

slept all in 100% cotton and this morning my hives were the best

they've ever been in a while, and I wasn't even taking any medication

since I was going to the allergist today. Plus, yesterday the only

un-cotton thing I was wearing was my underwear and that's where the

hives were the worst

That makes me think that maybe my hives are caused by synthetic

fabrics. Has anyone else had this?
