I have had Hashimoto's for 12 years. Take Synthroid 100 mcg daily. For the last four weeks, experiencing neck and upper chest pressure and discomfort. Thyroid Sonogram on June 17 (one week ago) indicates multi nodular goiter. Appt with Endricinologist in Pittsburgh, PA on July 20th, meantime, this pressure and discomfort is uncomfortable and constant. TSH levels within normal range. Advice? What is this pressure about?
