I can only tell you my condition of my lymph node at the time I found Dr B. My lymph node was very swollen, stuck out of my neck. It really had me concerned, I though I was fighting an infection. When I went to see Dr B, he said it was inflammed because of the lactic acid build up due to all of the inflammation. He sent me home with a tens unit that did not stimulate the nerves, but worked the muscles, flooding the muscles with fresh blood and oxygen, pushing out the build of yuck. Since being in treatment with Dr B, I no longer have a swollen lymph node. It is so nice. I am in no way saying that is what is wrong with you or not, but just sharing what the problem was in my case. I would however, seek a 2nd opinion on this before surgery is done, maybe even a 3rd.
I hope this helps
