I live in the Phx Az area & have the same thing. It's been going on for about 2 months now & the rash area is slowly increasing. About 3 years ago my job was threatened to go off to India, but was eventually overlooked last year. My company laid off 50% of the workforce quadrupling my workload & the stress has become unbelievable. I think this may have a lot to do with it. I live a very healthy life style and am very watchful about what I eat as well as what I put on my skin, but the stress is starting to undermine my health. Thus I am looking for ways to eliminate the stress as well as looking for another way to sustain myself. I have a drs appt later in the month & am hoping that they can diagnosis it. Are you under a lot of stress as well?
