For the past six months or so my skin has developed flat red circular spots that only appear after I get out of the hot shower or after I lay out in the sun. I believe the heat makes them appear. But after I lotion down they fade away. My skin has always been dry and itchy so I have always used lotion to soften it and relieve the itch. But these spots don't hurt or itch, they are just there. I was worried that it may be psoriasis, because I did some researching and discovered that beta blockers can trigger psoriasis, and I have been on a beta blocker (propranolol) for 5 years now. But the patches don't raise up.... These spots appear down the sides of my thighs, back of my calves, my butt, and a couple on my stomach. Any ideas of what these are?
