Underactive Thyroid
"I was on Cytomel for a couple of years. Then my dose got increased along with my Synthroid medication dose. I began having tremors, heart palpitations and tachycardia.  It was a terrifying experience! My symptoms almost entirely went away when going off this medication but, I feel as though my heart was dramatically affected and I don&#039;t know yet whether or not it was actually even damaged."
