That may be true with other conditons too - my sister has a low BP and heart arythemia with what is called prinzmetal angina - and it seems her symptoms become more pronounced with the end of her cycle as well - so initially they attributed it to her thyroid or flucutations in hormones. I actually went through meno last year and never really experieinced anything other than no more cycles - guess I was too wrapped up in pain and other symptoms to notice anything but my tmj. Have you ever thought about maybe trying some OTC herbal or natural supplements that increase estrogen to see if that may have some affect on your symptoms?
