Welcome Jean
I hope you find this group as lovely and as helpful as I do.
I get mouth ulcers especially when my lupus is flaring, and I get a lot of mouth infections and tooth problems. I once had a very sore spot on my tongue which was a small gland that had swollen.
But I have never had the swollen tongue you describe. Is this a recent symptom? Perhaps you could ask your GP is there is anyone else that you can be referred to. My last two dentists did not know what Sjogrens was, so the rheumy referred me to a Sjogrens specialist at the dental hospital when the mouth problems started.
