luvpinkpeeps, my rash looks (or looked....I don't get it real often now) very much like yours and also got worse with hot showers or washing my face in hot water. I had traces of this rash years ago, and it was the first thing that caused by PCP to order a test to check my ANA level. That was years before I was diagnosed, though. My rash wasn't reall bumpy either - just in spots. I've also gotten a rash on my chest in kind of a 'v' shape. It looked a bit like I had been out in the sun in a v-neck shirt, even when I hadn't.
