Fine-needle aspiration biopsy (FNAB) of the thyroid is generally a well-tolerated procedure associated with weak levels of pain. However, pain may be very intense in some patients. The cause for the pain in these patients has not been identified. The hypothesis of this study is that there is a likely relationship between pain level and nodule depth during FNAB.
