Re: please answer... just had ultrasound!
Given the relative small size and the proximity to the parotid gland, I think there is a reasonably good chance these nodes, along with your elevated inflammatory markers, could be caused by Sjogren's syndrome, an autoimmune condition that affects the salivary glands and other glands that produce tears, vaginal secretions, etc. The inflammation can cause the fatigue and malaise. Others signs of Sjogren's are dry eyes, dry mouth, dry vagina, some with it get joint pains. I know you said you were checked for AI disorders, but blood tests for Sjogren's (SSA, SSB) are not often done, and they are negative in as many as 40% of those with it. I would ask that at least those blood tests be done, and consider seeing an ENT who might be able to rule parotid gland inflammation out with something else like a sialangiogram. Tenderness, heat and swelling of the gland (like in mumps) would also be signs of inflammation. Sjogren's can be diagnosed as well with a lip biopsy. If any of this fits with your picture, a short course of Prednisone (2-3 months) may be all that is needed to get the nodes to resolve. If the node does get biopsies, perhaps a needle biopsy from inside the mouth could be done to avoid incision on the face. I don't favor a wait and see approach, because you are ill and anxious and need some answers.
