My sister is getting one and asked me how painful it was and I have trouble remembering--maybe it's like childbirth! I know I was concentrating on not swallowing and maybe that took my mind off it. I can't remember how long the needle was in. 30 seconds? They had told me to take ibuprofen ahead and I did. I had been worried because I'd had uterine biopsies and the ibuprofen didn't seem to help at all. Neither did the vicodin. I told myself if I ever needed another I'd take TWO vicodin! I think I remember the thyroid biopsy as painful but not unbearable--not as bad as the uterine biopsy.
My endo doesn't like using a numbing agent--said it makes the thyroid "angry"? But I wonder if something like valium or xanax--an anti-anxiety-- or vicodin would help. She usually takes pain worse than I do.
