I've had chilblain's too - not a pleasant experience. I'm glad you got an official diagnosis, supported by biopsy, and can hopefully start on some treatment for it that will help greatly. This is a pretty good article on it, especially it's relationship with lupus.

Seems about 15% will develop SLE, and about 50% will also have discoid lesions. I think it is also strongly related to anti-phospholipid antibodies, so it will be important to be tested for those as well (if you haven't been tested already).
Take care and thanks for the update. I hope you get some help soon. Stay warm - especially those extremeties!
