Hi James, just saw the photos of the rash. My goodness it must be uncomfortable, not to mention on the palm of your hand and tips of fingers. I'm glad you were able to get in to a dermatologist sooner than September and hope it's relatively easy to clear up. I wonder what helped most, the steroids or the Benadryl.
It sseems so unfair that you are having all these complications and I wish we could make them go away for you.

Warm hugs,
