Lymph glands can swell from infections too, so it could just be that. I'm glad you are getting a second ENT opinion and I'm glad you got the CT scan done. That will tell you whether or not you need to have a biopsy.

Easier said than done, but try not to worry too much. I can't tell you what a hypocrite I am for writing that! I am the WORST for worrying! LOL! But I know whereof I speak on this! You've done your research, so now you just have to really try to put it out of your mind until your doctor's appointment. Keep busy. Learn chess. Read challenging books. Do a paint-by-number. Get really involved in and binge on a TV series on Netflix. Whatever it takes to get this off your mind until you can actually know something concrete about your situation.

Sending hugs and good vibes your way!!!
