I have flushes, beyond hot flashes, averaging one an hr, all day & 3-4 during the night. They have run many blood tests--all the obvious--estrogen, kidney, thryoid etc & found nothing. I am post menopausal many yrs & took estrogen many yrs, but it doesn t help w/this. If you have further suggestions please respond. Also I have quit any drugs that have side effects of sweats. RS
