I have not been diagnosed with SS, but have had positive ANA tests since 2006. I am requesting an appt. with a rheumy and hopefully get a more intense workup. I have tested negative for Lyme's and negative for HLA-B27. Testing with a high Rheumatoid factor, too. I am going to request some testing for SS, but one of my MAJOR complaints is the back pain that I have constantly. It's hard to explain...feels muscular, but I also sometimes get pinching in my lower back. It's almost unbearable when I first wake up, but I live with the constant aching back. Naproxen, advil, tylenol doesn't touch the pain. Vicodin does help, but not like I want to be taking that on a daily basis (although lately I'm starting to think that if I can live pain free by taking a vicodin once a day I might consider it). Good luck at your rheumy appt. I'll be keepig an eye out for what they find!
