Just got back from the doc. Not lupus, not rosacea, not any other gross-sounding skin ailments from legendary 1960's ad campaigns. Definitely not leprosy.
It is some obscure and hella strong allergic reaction, so I'm seeing another specialist, still on scary meds, still can't wear makeup, in fact have to avoid more stuff. Apparently even baby shampoo and Cetaphil are too risky for me right now, until we figure out what's the cause.
Thanks all for your concern and support, I really appreciate it. Oh, but the stitches did pull loose too early, and the biopsy site is still healing. So no poking me in the chin, okay?
