Hi Elaine

I wrote you earlier that I have Hashimoto's and was hyperthyroid after taking Synthroid (50mcg) for 5 months. My endochronologist said the Hashimoto's was causing it and not the Synthroid because it was such a low dose. So I went off the Synthroid for two weeks to see what happened and I am now in perfect euthryoid range. TSH is 1.6 and T4 and T3 Total came back right in the middle of their normal ranges. Yay! I have an open lab paper and have been told to have my levels tested again in 2 months or sooner if I start feeling symptoms.

I've been feeling pretty good until today.

Today I experienced some pretty uncomfortable lightheadedness, slow heartbeat (58bpm), and mild chest discomfort. Felt anxious and like I was going to pass out. I asked my endo about it at my appointment today. She said my heart was beating regularly when she checked it and said it probably wasn't the thyroid issues causing it.

Sounds to me like maybe bradycardia? Isn't that related to hypothyroidism (which I am not at the moment, I suppose)? Do you think there could be any relationship between this and the bouncing around my thyroid's been doing lately?
