SjoDry, just a thought, when did your Sjogren's symptoms start? Mine started after I began use of CPAP and am concerned about a connection. CPAP creates a fully plastic enclosed environment (lots of chemicals) that forces air directly into the mouth, nose and lungs, putting pressure on the ear, nose and throat constantly for 8 hours a night. I have been on CPAP for a year and Sjogren's was just diagnosed. I've had general dry eye and low grade sore throat in past, but didn't have the severity of the Sjogren's symptoms before CPAP. I'm just starting to wonder about this so am searching to see if others have noticed a connection.
