Hi Wallaby,
Let me also welcome you to the SJS World and family! As Bucky said, please do look around as there are just tons of topics and oodles of information that you might find interesting.
Oh boy, does your story sound oh so familiar! For me it started with getting my hypothyroid diagnosed as Hashimoto's for doctors to start listening to me. I was lucky to get a rheumy that started me on Plaquenil on symptoms alone, and when she left the area, the next rheumy continued me on Plaquenil.
I am also diagnosed with SICCA, but that's okay, I'm still being treated as though I'm positive, and hey, SICCA is a diagnosis too. Now to get these darn dry eyes under control!

Take care -
Patze
