Two months ago I had one lymph node removed, the one underneath my jaw on the left side to be checked for lymphoma. My only symptom was this one lymph node, very very very swollen, and it was pretty painful. The biopsy came back cancer free. The discomfort in my neck never went away, and has now spread to my right lymph node. I can't really tell if it is swollen, because I have nothing to compare it to. The discomfort comes and goes but in sharp spurts. Pre-surgery the only thing that showed in the CT scan was the swollen lymph node which was then promptly removed. What could this be!
