Oh, the joys of the fine needle aspiration biopsy! The radiologist who did mine on my thyroid nodule did six passes with six separate needles. Yes, they had me numbed up, but it was still intensely uncomfortable, and then I went back to work looking like I had a giant hickey on my neck from the bruising! Gah.
Anyway, thank the Lord, my nodule was benign, but it did necessitate the removal of the right lobe of my thyroid. And that's the treatment of choice, really, because it can be darn difficult to tell what kind of structure you're dealing with, just from an ultrasound, or even from an FNA.
Remember to get a referral to a surgeon who does a *lot* of these surgeries. My incision is about two inches long and is hardly visible, now, almost three years down the road.
