You are going to the right place. When I went to my GP for the "pressure in my neck and throat" he panicked and sent me to a Cardiologist. Long Story and they were going the wrong way with my symptoms.
A CT scan and then Ultrasound is what finally showed my nodules.
Try and stay calm and see what they find. I am great at saying Stay Calm when I am so high anxiety myself !!! LOL
Please let us know what happens on your Appt. Good luck. Think Positive.
