It can be scary the first time, and more. I would suggest that you mention this to the doctor/nurse if they don't ask. Also mention your nervousness about the procedure. My doc was willing to go slow and talk me through it so that I was able to be as comfortable as possible. If you take meds for anxiety, you might want to talk to your pdoc about doing something specifically for the doctors appointment. I also talked about the whole experience with my T so I would know exactly what was going to happen and we talked about what I could do to relax. I took my anxiety balls to give me something else physical to focus on rather than what was going on. Good luck!
