'Sunburn' rash

over the next 2 weeks the red spots developed more across chest, arms & groin.  Also developed what appeared to be a separate rash, bright red, like sunburn and very itchy.  This was first noticed on thighs, then torso and arms.  It was soon more dominant than the red spots.  It covered most of arms and torso but there were gaps on the inside of the elbows. I had also developed very dry scaly hands
