Geez that's crazy @alaskahippie! Gotta love the advice from the dr's too! Wow, that's the best they could come up with?? I get crazy heart palpitations as just one of the joys of menopause, but never any pain with it; it just feels like my heart beats like crazy but with absolutely no patter, just all over the place. It only lasts for a few seconds though. Hope you get to the bottom of it all ... having to wear those masks with air quality so poor is brutal as well!
