No problem! :D I can sort of relate -- I'm rheumatoid factor negative, but have all the clinical signs, so my actual diagnosis is seronegative rheumatoid arthritis. I am ANA positive at like 1:80, one of the tests often used to diagnose lupus, but they think the Graves' is what's causing it.
The only other thing I can think of it the connection of frozen shoulder and diabetes, and has your GP checked your glucose? And since Dr. Waltuck is still at Emory, and there's a big focus on teaching and info sharing, he can probably connect with him via the American College of Rheumatology or something.
