I have been feeling a fluttery feeling on and off directly in the region of my heart for the last few weeks.  No pain, no breathing problems or anything else.  About 3 weeks ago I saw a Naturalpath doctor and she put me on Nature-Throid 1/2 grain daily based on blood test results and symptoms.  I have felt quite a bit better except this started.  This is something on and off I have felt before but now it seems daily.  Any relation?
Thanks for your question on Chat Doctor. I can understand your concern. You are mostly having palpitations. It is rapid heart beating and this can give rise to Fluttering feeling in chest. And yes both these might be related. Your symptoms are sorted only after starting thyroid tablet, so we should first rule out high levels of thyroid hormone because this can cause similar symptoms of palpitation. So get done Free T3 and free T4. If these are elevated then you need to stop that Chat Doctor.  If these reports are normal then get done ECG to rule out arrhythmia (rhythm disturbances in heart) because this can cause palpitations. So consult doctor and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks .
