I know that allergic reactions can stick around for awhile. My mom is allergic to bee stings and years ago when she was stung by one, she had hives that would randomly pop up in various areas all over her body for about a month. She had to take a lot of antihistamines for a month or two.

Last year, she had allergic reactions that we never did figure out what was triggering them. She'd be minding her own business, and all of a sudden the side of her face would be swollen and we'd be rushing her to the ER. (we suspect it was the Clinique makeup and soaps she was using)

So, if you had a reaction to a latex bandage, could it be possible the reaction is still floating around in your body, triggering the hives, even tho you've removed the latex?
