Salivary gland issues

I have Myasthenia Gravis
Antiphorpholipid Antibody
Bronchitis
Chronic Anemia
Mixed Connective Tissue Disorder
Frankly my Sjögren Disease was always a back burner issue. Primarily salivary gland stones however now I have developed an anomaly in the salivary gland under my check it showed up in a routine MRI . I had had discomfort in that ear running down my neck. I wonder if others have had this issue it does feel better with a heating pad on my neck. Heat makes everything feel better! Judy Crais
