Hi Helen,
Good luck with the Clinic. I've had ultrasound guided FNAs twice, both times for suspect nodes. One came back negative (falsely) and one positive. You're right in that they wouldn't be doing the test unless there was something suspect. I'm very suprised though at how long you have to wait for the ultrasound appointment. Perhaps you could get the Doctors at the clinic to speed this up so you can stop climbing the walls.

Best of Luck
