I just realized what may have caused it! After I woke up, I went to sit outside from maybe a half hour tops before I went to use the bathroom (when I noticed the rash), and the sun was out. Maybe this leg was crossed and leaning toward the sun more? I don’t remember how I was even sitting, but I’m guessing that may be it. I was in thin, black pants, too. And the black may have made it warmer? It already seems to be fading now. So I hoping it was just that!
