I would say your best choice is to wait for the biopsy results. Skin conditions can be tricky and a self-diagnosis is a bad idea from exprerience. I have been diagnosed with Pemphigus Foliaceous after a biopsy. But before the results came in, I had had about ten false diagnosis. 3 of them were from doctors who said it was just a skin infection and kept me on antibiotics. The others were my own and my friend's bad diagnosis. I spent a lot of money on antifungal medecine, and antibiotics. I had all the symptoms of a fungal infection, but it just wasn't. So your best bet is on the Biopsy. I would wait if I was you.
