What Causes Itchy And Sunburn Like Skin While Having High Blood Pressure?

on occasion, I wake up feeling like hot with itchy skin. I look in the mirror and I look like i have a sunburn over my entire body. Body lotion will provide a temporary relief, The symptoms will gradually disappear after I'm out of bed. The home heating system has been on and the house humidity is probably low. I also have high blood pressure. I have experienced this condition twice in the last four month.
