The rash was red, dry, itchy blotches that began with a single roundish patch on my upper arm/shoulder that appeared a few weeks before the rest. It the spread all over my chest and neck, with one or two on my legs arms and stomach. This lasted around 6 weeks before disappearing almost completely and very quickly. Now, 4 or so weeks later, it's appearing on the back of my hands and wrists as well as my arms and chest. Is this characteristic of PR, and how can I finally get rid of it for good?
