Cold allergy is a condition in which antibodies that trigger the allergy can be activated only when the body is exposed to low temperatures. The condition can not be cured. The goal of the treatment is to reduce the number of episodes. Thus, avoiding cold weather, having you (especially the hands and feet) covered with warm clothes, avoiding getting in touch with cold objects (even very cold water) is the only thing you can do to prevent the allergy from occurring. When the allergy rush appears, antihistamines are all you can take and need to improve the condition.
