I was diagnosed hypo 6 years ago. Tried Synthroid & symptoms were still there. My doctor put me on Armour 3 yrs ago. I loved it all symptoms were gone except the weight & fatigue. I developed terrible heart palpitations while on Synthroid so when I switched & noticed that had stopped, I was excited! Well, last year I ended up in the ER with PAC's & reflux. I was told they were normal. Saw my doc & was diagnosed with ADD. I've been on adderol ever since. What in the world? I've tried to get taken off with no luck. Won't a stimulant make my PAC's worse? Thyroid effects the heart anyway. My heart flutters all day, everyday. I'm worried. Any advice? Sorry for the rambling.
