I have had on and off itchy skin for years... I'm always super careful about the lotions I use and I haven't changed anything lately....but suddenly I am so itchy! I can't stand it....normally taking a benedryl helps but it isn't doing anything. I never get a rash and no one has been able to explain it.....does anyone else ever experience it? It is itchy across my chest/collarbone and upper back..... I could scratch all day and not get any relief. Anyone had this and figured out some relief?
