Have they run an autoimmune panel on you? Check out www.lizajane.org . It's a listing of testing that can be done. The rash might be indicative of vasculitis. Also read the stickies at the top of the page. They are full of years of info by a lot of people who have been there and done that. Also, gluten intolerance is a possibility.

I'm sorry you are suffering so. A lot of us can relate very much.

The weekends are slow. It's also vacation time for some folks.
