Lump on neck?

hello all!

I just wanted to see if anyone has had some experience with lymphoma or Mets to lymph nodes. I have had a hard, immobile, not painful or tender lump on my neck for about 2 months. Night sweats worse than normal (not totally abnormal bc of surgical menopause). Some headaches, but also not totally abnormal for me. I have not been sick and no other symptoms.

Saw onc on Friday last week and wbc were higher than normal, and neutrophils were pretty high. Have a CT scheduled for Thursday morning. I would say it is on the larger size maybe close to an inch across? Hard to tell though.

Freaking out here!!!
