My husband has had a sunburned feeling for over 4 yrs. It used to be once in a while but it is all the time. it does ease up at night when he takes his clothes off and slides into bed, and we keep it cool in there. In the morning when he gets up. it is there but not as bad , But when the day goes on. it get more intense. Any suggestion? He has brought it up to several of his doctors and they can't figure it out Please help!
