Started to feel a little worried today, my t4 has been high for months and they were going to start treatment but my heart rate is 45 which they say is unusual for overactive. Basically they have no idea what is causing this. I am feeling the cold, not the heat and i have put a little bit of weight on which again is the opposite of what should happen with an overactive thyroid.
I do run a bit and generally quiet active but I do not feel fit enough to have an athletic heart rate of 45!
Any ideas welcomed.
