There wouldn't necessarily need to be another allergy, since people can
have an allergic reaction to heat or cold itself.

Subject: Re: Maternal Hives
I have a mom who gets hives if she's in a cold room or outdoors when it's
below 70 degrees. She's found that taking 5mg OTC claritin daily will
prevent the hives nearly all of the time. She's now beginning to explore if
she has some underlying food allergies/intolerances that are stressing her
immune system to have this unusual reaction.
