Hi doctor actually I have figured out that I am suffering from chronic urticaria in which hives comes out frequently in cold season especially winters , ie- December to Feb . The two most certain causes which leads to hives in my case are Exposure to cold wind and exertion / movement of body. I just want to know about how can it be temporarily relived and thereafter permanent relief ! I know about Antihistamines that prevents the flow of histamines causing hives but that is only a temporary solution to the disease/allergy.
