Sharlee - Not sure if this will help, but I also had an enlarged lymph node, found during my F/U visit at MDA in Dec. Dr. said to have an FNA done at Emory if it didn't go down in a month or so. In the meantime, I had an ulcer on my tongue (see previous post) and a subsequent bx of that in early Jan., which was benign but right after that another little lymph node popped up. So I had US guided FNA on the larger original lymph node, but they too said the small one was too small to do an FNA or biopsy, and the thought was it was a result of the ulcer/bx. Both my ENT here in Atlanta, the Emory drs and 2 drs at MDA agreed it was nothing to be concerned about....
Do I still feel it and worry sometimes? Of course... but that's the nature of this beast, I guess... so I understand how you are feeling...
