Good news that it's nothing serious but it sounds just like my prognosis, You're On Your Own! Moisturizer is what they told me to do also. There was a trigger that set off whatever you're experiencing now because there's always a trigger. Unless you get lucky like newmedman did who was able to figure out what he was allergic to so he was able to fix it by himself. I think what you and I experienced is way more common and frustrating among people who suddenly break out in an undiagnosed crazy itchy rash and doctors don't have a magic pill to cure us or understand why it happened.
