I'm scared because whenever i go outside my body itches will i die and can you tell me how i will be able to cure it before it gets worse thank you wh?

Allergist: Going outdoors with the resultant temperature change and/ or certain activities may release histamine or other substances that causes the itching reaction. Apparently you don't break out in a rash such as hives or angioedema. Taking a nonsedating antihistamine like claritin (loratadine) before you go out may prevent this reaction. An allergist is best qualified to evaluate and advise you.
