rsunburn like rash from elbow up to where shirt sleeve ends. does not itch but have had it for months a sunburn like rash . Does not itch, maybe rarely. So not sure if its a normal itch or the rash. It starts right where a short sleeve shirt stops and goes to my elbow. nothing raised like bumps. Just red and when I go in the heat and come back inside its redder. Then seems to calm down but still looks like a sunburn. no where else on my body. Iv had this now for at least 6 months. dermotologist said just my body. I can t except that . There is a problem. My regular doc told me to stop blood pressure med and vitamins and caltrate. Thats all I take. But stoped that for a week and no change. had to get back on bp med. Can you help me figure this out?
