I had three fna's in total...and i am a firm believer that, it depends on who performs the fna. My first one, sent we home from work for the day..(i worked in a hospital)..it was horrible. I was in so much pain afterward, i couldn't focus. I was sooo nervous the second time (2 yrs later), and mentioned it to the surgeon. He explained that he always "numbs" the area before performing the procedure. Due to that, i was ok. The third one was 6mos afterthat, and this surgeon performs it in his office during the visit and it happened so fast, i barely noticed...however, the area swelled a little and was sore for a few hrs afterward, but i was ok...It's normal to be sore up until a day after the procedure..but it will fade away.
I had issues after the FNA I underwent... I was raspy and swollen...
You could try some aleve to see if that helps...
