Nancy: They did a biopsy. It was diagnosed as granuloma annulare.

The doctors don't know what causes it, they say there is no cure (some people report it goes away magically by itself after a decade or two), but it's not life threatening and not enough people have it to make research profitable. Well, after 26 years I found out what causes it - wheat and other floury, gluteny products. And I found out what cures it - don't eat them! No expensive research projects needed. I told a couple of doctors, who smiled and nodded kindly. Gah.

Stacy: Absolutely, let's get those substances out of our homes and let's keep 'em out. Hope your joints feel better soon - which, of course, we both know they will. Good luck to you too!
