question: I have a rash on my face, neck (behind ears only), and the top of my arms and one hand. In areas that are exposed to sunlight. I ve been on prednisone 40mg for 7 days, and stepped down to 30mg today for the next 6 days, then 20mg,etc. It does not appear to be working. No itch, no pain, just very dark at times and I m self conscious of it as it is very noticeable. I had a positive ANA test but not sure of how high it was. No joint pain, or any other issues. Rash started as small bumps on neck after boating, they have since joined into one large dark red blotch behind each ear about the size of a baseball. Need some help and advice.
