I can appreciate your concern about your lymph nodes. It sounds like your doctor is being appropriately cautious. I just wanted to mention that it's not uncommon for enlarged lymph nodes to be associated with sjogren's syndrome as well as lupus and lymphoma. I was recently dx with sjogren's, and my doctors, and dentist, routinely check my lymph nodes for enlargement. Of course, having sjogren's also puts you at risk for lymphoma, but I believe it is a small risk and simply requires surveillance (which you are already getting).
I believe your lymph nodes can also be enlarged because a simply virus or bacterial infection. Whenever I'm sick, the lymph nodes around my neck area get very tender and sore, sometimes enlarged.
In any case, I hope you feel better soon, and that your doctor finds out exactly what the cause of your enlarged lymph nodes are. Please let us know the outcome(s).
