good news, bad news.

good news: I do not have any form of lupus or any disease that is causing my sun allergy.
bad news: because I don't have lupus or any disease causing my sun allergy, they do not know what is causing it.

terrific.

even better news: I'm supposed to wait until it happens again and let them get a biopsy.  i'm tickled pink, let me tell you.

but, at least it's not lupus. that's the bright side!
