Dear Doctor, I am allergitic to sun and traffic smoke. I get severe itching whenever i go out and come home. When i am in college almost 11years back a sun burn have come on my wrist. Which was not gone but did create any problem. It generally itches when expose to sun. Since a week even though i don't go to sun, this is itching and the skin had become so rough. These days this seems spreading a bit. I generally don't apply any lotions to my body. Thanks Durga
