I tested positive for antibodies in 1999, but at that time my TSH, T3 and T4 were normal. In 2004, my TSH was elevated
and I was started on
Synthroid 50 mcg. I also had an ultrasound at that time which was normal other than the thyroid gland was at the upper limits of normal size. The past few months I have been experiencing symptoms of anxiety, panic attacks, palpitations, tachycardia, and sweating along with a feeling of fullness in my neck and some minor discomfort.
