No definitive test results

I hope I am doing this right. I have been diagnosed with Sjogrens for years but without definitive test results. I have dry eyes, ears, nose, mouth, etc. I also have a rare disease called Fibromuscular Dysplasia which seems to come along with various assortments of other connective tissue disorders such as ehlers danlos, arthritis, and other assorted things. I do not test positive at this point for either RA or Lupus but my rheumatologist says it is Sjogrens. I also tire easily but that can be a result of FMD as well since my carotids are compromised. Any suggestions?
