Since about Monday my skin has been acting very weird. It started out taht my face would turn very red, and it would not itch but it would be very warm. The day after that, mainly on my forearms, raised red patches of skin appeared. They are not itchy either and they don't cause me any kind of discomfort, theyre just there. The same goes for my upper arms and back. I had eczema when I was younger, so I tried using an eczema lotion but that does not seem to help. THis does not feel at all like the eczema flareups that I'm used to. What's wrong?
