Oh my goodness I hope you have found something out by now!
I just wanted to mention that I do think a gluten free diet did help me some with my lupus.. Before I knew I had lupus lol. I was dx was Graves disease in 2007 and then Celiacs disease in 2008 when it was really more than likely the lupus all along. I did go gluten free from 2008 until about 6mos ago when I got my lupus diagnoses and also had some stomach biopsies confirming I probably never had Celiacs disease. BUT from 2008 up until the end of 2011 when I had my son, as far as I can remember, I really had no symptoms. No rashes, no inflammation, no weird mystery stuff.... So I have no idea if it would work for you at ALL but it might be worth a shot?? There are some really good gluten free pizzas I can recommend!
Graves Disease 2007, Ceilac's Disease 2008, Lupus 2012.
