Oh Hope I can believe menstrual cycles can make PN worse. I know it can make it worse with other types of health issue too. So definitely with your body going through changes will aggravate your PN worse.
I did not get the night sweats, but the hot flashes are miserable. Those are the time you want to stick your whole body in the freezer.
So sorry to hear that it is affecting you hard, and glad to hear that you are talking with others about it. Don't know what exactly phrase you are in menopause but hopefully it will pass soon.
