My face comes out in some sort of rash everytime I go outside. When the weather is worm it is not too bad, but today was very bad. My ears swell and goes red and hot, and my face looks as if I've been beaton with a stick. I have been to see my GP but he has no idea why. In saying that he has prescribed allergy tablets for me to take which does work, but I really don't want to be taking them for the rest of my life. Can you help?
