Jac,
Well I'm learning like you are - yes the hormones can do this. I have the tinglies real bad at times and the heart attack symptoms come and go. I've been reading alot about peri and it can cause all sorts of problems - anxiety, gerd, ibs, heart palps and tinglies not to mention unwanted hairs in strange places, gray hairs growing like weeds, flabby, itchy skin. Guess it's just another chapter in our book, huh?
You're not alone!
