UPDATE:
I spoke to my ENT's office and they said I should see my GP and call back (which I did today).
She has no idea what caused the node to swell and the itching etc. No one seems to know but this whole thing seems to be systemic as it's now progressed to my chest. I'm a little hoarse and my ears itch. Their best guess is "something viral". I was given an antibiotic to take anyway.
I discussed the "scanxiety" with my GP and she's not surprised at all that I have a bit. The med she gave me is one I can take whenever I feel I need it so I can start a week or so prior to check ups and go off afterwards. There are no side effects associated with it as it's not an SSRI and mild by med standards.
The good news is that the CT scan was "unremarkable" and my ENT said not to get the biopsy and to see him again in May. If the node persists or grows larger contact him but for all intents and purposes, I'm Ok for now.
Can you say ~WHEW~?
