I spent the night in the ER about 4 weeks ago after having chest pains and was told that my TSH level was at 63. They gave me
IV synthroid and told to take my prescribed
dosage. I followed up with my GP and was told to increase my dosage of synthroid to 150 mg until they got my blood work back. The next day my GP told me to take 150 mg 6 days a week and 300 mg on the 7th. After 3.5 weeks (while at the gym) I started to have chest discomfort.
