Salivary Gland Issues

I have:
Myasthenia Gravis, Antiphorpholipid Antibody Bronchitis, Chronic Anemia , and 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!
