We still never figured out what was causing the rash I had. The dermatologist gave me a steroid cream which made it go away, and it stayed completely gone for about a month before cropping up again, in mild form which disappeared after two applications of the cream (just saying that makes me feel like a rulebreaking baseball player). So no big deal, but I still wish I knew for sure what was causing this so I could make it go away for good and not have it as a niggling worry.
