I am 45 and have been having these symptoms for aabout a year, maybe longer. Just before, during
and after period
and also at ovulation time I experience very unsettling anxiety, heart palps, and this other feeling (not sure what it is), feels like I can't breath, heart races, can't get a deep breath, feel hot in my face, etc. It will last just a few seconds and then it happens again about 15-20 minutes later.
