Re: Does this sound like Sjogrens?
Depends...if you've had dry mouth for a long time, and dry eyes, might be sjogrens, particularly the part about mouth sores and trouble swallowing. Reynauds and feeling tired can be related too. I think your rheumatologist is saying they aren't sure one way or the other, they won't dx it unless they are sure, and no dry eyes means you probably don't have sjogrens.
The anticentromere ab is linked with crest syndrome/sclerodoma. I don't know much about it, but just googling it right now, you do have some / most of the symptoms, so you might want to look into it...
