As Lynn said, the biopsy itself isn't too bad. It's not fun, but not horrible. Don't hesitate to ask for more lidocaine (numbing agent) if you feel you need it. I drove myself home. My neck was a bit sore afterward, but after keeping ice on it for a little while, it was ok.
Hopefully, this will turn out to be benign. Good luck to you!

The biopsy itself isn't bad. You should find out the results within a few days.
In my case the biopsy wasn't definitive so I am having left lobe of thyroid removed (and possibly all depending on what they find).
Keep in mind that most nodules are NOT cancer, so just try not to worry while waiting for results.
Good luck!
