Three days ago, my 23 year old daughter was diagnosed with Hyperthyroidism by blood tests (no scan done) in the ER. She had increasing symptoms of anxiety, sweating, palpitations, weight loss, fatigue and muscle weakness. At the time of diagnosis, she had no thyroid enlargement. They started her on PTU 50mg QID and Propranolol 80mg BID. Since then, her thyroid has significantly enlarged, where it is visually obvious, and she is now complaining of a sore throat when swallowing. Is this normal after starting treatment, or should we go back to the ER?
