Hia!
How long have you been on this regime? If it's for not that long your symptoms may decrease or go altogether.
But if it's been a while then as I'm doing now taking a break may help you resolve where the issue is.
Interesting that your Doc says palps are from estrogen. I had palps, I'm peri, had them before taking hrt but after replacing some of my estrogen with 1 pump E gel it resolved. I have however had to stop taking all hrt instructed by Doc, in the last week after 7 months on it as my wind, bloating and diarrhea have been out of control. It's so hard to work out what my body is trying to tell me, with these symptoms, there seems no rhyme or reason to it, I think I've nailed the reason and then I'm wrong. As yet to find the smoking gun.
Wishing you better luck than me in finding the answers, and sorry your suffering these symptoms, the palps are scary but not a symptom that's linked to heart attacks so don't worry too much. x
