Hi Dana,
The rash has faded a bit today --

Only flares if I take a hot shower or get overheated. That is so strange.

It's only over the past year that I have had the rash issue. Actually this puts my mind at ease knowing that I don't have strep every time I get this horrid rash. So, this is just a question that may not even have an answer, but does our body chemistry change as we get older and/or have children (I have two) that these things happen to us out of the blue?
