Periodically, I get a rash- raised patch that itches and burns. It's usually occurs in the same areas: below the knuckles of my right hand, on thumb and middle finger. Also on the back of my right leg halfway up. Why always the same areas? I have used Fluocinolone cream which burns before bed, and in the morning, I'm clear, Then it begins again midday. Any ideas would be appreciated. (I've had this on and off for several months. I've also had it behind my left knee, but that's OK right now.)
