Well, I am 47 and have had weird upper body flushes for several years now on and off. Mine usually is around my neck area. And at the same time I get weird chills on just my arms. And my periods have started doing weird stuff for the past year or year and a half now at least, maybe two years. I have had several times where I have skipped periods. And I periodically notice palpitations. Here is a link to a website that I frequent that has to do with menopause.
