waiting for answer. Would be great if you can take a sec and
answer them
How do I prevent this "allergy"?I have a strange allergy. I'm sure if it really is an "allergy" or what it is. When ever I'm in a colder place, I get hives. All over my body, and they itch. My skin gets red as well. I went swimming today and it wasn't really even that cold, but I got them again. It isn't only in water. Walking around during the night, I can feel my neck or anything exposed getting itchy and what do you know. I'd just like to know what it's called and how to prevent it. It's kind of unsightly and a little embarrassing. Any help would be greatly appreciated. Thanks a bunch!

Doctors refer to this as cold urticaria (ur-tih-KAR-ee-uh). It's also sometimes called cold allergy or cold hives. With cold urticaria, exposure to cold temperatures causes redness, itching, swelling and hives on your skin. As much as possible, people with cold urticaria should avoid exposure to cold air as well as cold water. For example, swimming in cold water is the most common cause of a severe, whole-body reaction — leading to fainting, shock and even death.
Medications used to treat cold urticaria include:
1) Antihistamines. These medications block the symptom-producing release of histamine. Some of these medications are available over-the-counter, whereas others require a prescription. Examples include loratadine (Claritin), fexofenadine (Allegra), cetirizine (Zyrtec), levocetirizine (Xyzal) and desloratadine (Clarinex).
2) Cyproheptadine. This medication is an antihistamine that also affects nerve impulses that lead to symptoms.
3) Doxepin (Sinequan). Normally used to treat anxiety and depression, this medication can also reduce cold urticaria symptoms.
