oh wow butterfly,
what a week you have had. I know what you mean about everything that is happening in your body and worrying you and those who care for you. I was in a really bad flare last fall, and i was in and out of the er, all kinds of specialists checking everything, and i came away with "it must be your lupus." So incredibly frustrating, but at the same time, relief that there is not something critical going on. Hopefully your flare will subside and you will be given some time to get your body back in synch....
what type of discoloration are you experiencing in your leg? I know this had to really frighten you.
take care, i am glad you are at home and can sleep in your own bed....there is nothing like our bed.
