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. It can happen only once or 2,3 times spaced apart and then not happen again until this time next month. I've been told this is a type of tachycardia (sp). But it ONLY happens just before, during, just after menstrual cycle. I also have night sweats, and sometimes cold chills. Last night I kept waking up feeling anxious and when I got up this morning my hair was damp from sweating. Mood swings are horrible. Will all this go away once I am "officially" in menopause and not having anymore periods? Or, does it continue through menopause as well? Oh, and my hair is breaking off and thinning. Is this part of perimenopause as well? Thanks in advance for any replies. I greatly appreciate them.
