Liken unto lichen

So all right, I've got some kind of pox. I've never been to a dermatologist before, and if they're going to insist on hacking bits of my flesh out, I may not return. In May I got some unknown rash thing and two months and $300 later I have been tentatively diagnosed with Pityriasis Lichenoides et Varioliformis Acuta, or PLEVA. I have a disease with an acronym. And yes, "lichenoides" means "like lichen," the stuff that grows on rocks. Sigh. It's not contagious, it doesn't itch or hurt (except when they carve bits of it out of me at the doctor's office), and it doesn't occur enough to warrant enough research to know what causes it. It's just irritating and ugly, though the really hideous spots are confined to my ass. And apparently it'll go away by itself, but no one knows when. My health has been going downhill since age thirty. I feel like a leper.
