Re: 2.8 cm thyroid nodule!
That's a great idea to go to the ENT! The pcp shouldn't give you a hard time---just say, the timing for the endo is several months, and you can get into the ENT much faster, and the ENT can order the fna (needle biopsy) that you need next. If the doctor would refuse (which I doubt) I would ask them to get you into the endo. sooner.....then they will realize why you've done this.
There's urgency, but no emergency. Most of these nodules are benign, but yours is on the larger side, and you do need a needle biopsy (It's a quick procedure, usually in office) to determine the next step, and you do, with that size nodule, need an ENT/surgical consult anyway.
I had a 2.5cm nodule, found it in october, got my fna results end of december! Got my thyroid out several months later in february----mine was that rare situation of cancer, but there was no emergency, and it's years later, and I'm no worse for the wear.
Good luck getting your next appointment with the ENT, and try not to worry too much, just go through the steps of the process.....you will be okay, no matter what.
