Do you have any other symptoms, such as dry mouth, dry or irritated eyes, vaginal dryness, difficulty swallowing (eating dry crackers), dry skin, burning or pins and needles in your feet/toes, sweating issues, sun sensitivity, rash, etc. These and other symptoms can be symptoms of Sjogrens.
Just for the record, the SS-A and/or SS-B can be negative in up to 50% of people who have Sjogren's. So, just because you have negative SS-A and SS-B does not mean you do not have Sjogren's. A lip biopsy (minor salivary gland biopsy) can be done to confirm Sjogren's.
There actually are no specific blood tests for specific Autoimmune Diseases. The tests can help corroborate the symptoms to come up with a diagnosis, but no one blood test will state definitely that a person has a specific Autoimmune Disease.
Your Rheumatologist should test you for all of the various markers that can be positive in various Autoimmune Diseases. You could have another Autoimmune Disease instead of Sjogren's. I had about 40 tubes drawn after my first Rheumatologist visit. She checked for everything because she knew something was wrong and she wanted to find it. Be sure you have a Vitamin D level checked. Most people are Vit D deficient and Vit D deficiency can cause a lot of symptoms. Also have your thyroid checked because thyroid problems can also cause many symptoms and problems.
Hope you find the cause of your symptoms so you can get treatment. Best of luck.
Well, the good thing Lisa is that if the symptoms are from HCV, there is now a cure. Hope you get your answers real soon.
It is possible that your symptoms are from HCV due to a blood transfusion in October of 1991. The blood supply was deemed safer after June of 1992. I don't know how much of a risk this would be as your symptoms can be from any of the connective tissue diseases. I hope you get to the bottom of this and you start to feel better real soon.
