I’m not a doctor, this is just a support group. Having said that….Why don’t you see a rheumatologist? Noting your other symptoms would be important. If it is Sjogrens , a significant number of Sjogrens patients don’t get diagnosed until lip biopsy. Depending on where you live, it can take time to get appointments with professionals, who do that kind of thing.

You can get a blood test to find out, although they are not 100% reliable. If you have the symptoms, you have Sjogrens; my mother had it and 2 sisters and myself have symptoms of it. My symptoms are Burning Tongue (look up the picture/chart of that on the Mayo Clinic chart of tongue pictures. Along with that we have Burning Vulva, Dry Eyes and Dry Mouth. Amitriptyline at night gets rid of the burning vulva part and I use Thera Tears (my eye dr.'s choice) for day and the nighttime ones before bed. OraCoat's Xylimelts keeps the dry mouth under control at night.
