I was going through many tests to see if a nodule was benign, I kept being told it was suspicious. A friend referred me to Dr. Yeh. I set up an appointment. An ultrasound determined my parathyroid had entered into my thyroid. Because of his expertise, Dr. Yeh was able to find this. A few weeks later in surgery part of the right thyroid was removed.surgery After it was so amazing - my allergies decreased, and got my energy back, Pain I had had in my neck for 10 years was relieved. My TMJ is relieved. I feel so much better- it was meant to be! A good success story!
