I presented exactly the same way as you have. Positive SS-B, speckled ANA, negative SS-A. My GP was convinced,(based on my symptoms of extreme fatigue, muscle weakness and joint pain)before bloodwork came back, that I had Lupus. I was a mess. And still am most days.
I got referred to a rheumatologist who said that my bloodwork indicated Sjogren's Syndrome not Lupus.
Yes, you can have it without the dryness issues. In fact, a lot of people don't get the dryness till much later.
She threw me for a loop when she said that although I have positive blood work, she sees evidence of something else autoimmune and she thinks the Sjogren's Syndrome is secondary to that. I don't have a label for the predominant autoimmune disorder (she calls it overlap) and I'm ok with waiting until it rears it's ugly head in my bloodwork and I get a name for it. She treats me with Plaquenil and steroids during severe flare ups. It's important to have a doctor who'll not only treat based upon bloodwork, but will rely on symptoms as well. DragonflyC is correct in that treatment is the most important thing.
No one wants to be on medication but please give the Plaquenil a try. It's the first drug rheumy's try for a variety of autoimmune conditons. Also, it's a disease modifier, so you may be catching the autoimmune process in time before it advances to a stage where you don't want to be. It, like many other medications has it's side effects, but it has a lot less than the other drugs to manage this and other autoimmune conditions.
If you take it, remember to always take it with food and get your initial eye exam (and every 6months thereafter). I wish you luck!
