New onset ‘hot flashes’ years after menopause

I’m 67 years old. Have had ongoing hot flashes since I was 52. They were frequent (all day long) for the 1st few years. After that, once or twice a day. I was able to tolerate it so did not seek medical treatment. But just this year, the hot flashes stopped and I my body went haywire. Started with a terrible skin condition mostly on my arms spreading up various parts of my body. 3 months later, developed severe anxiety disorder. As you may know, hot flashes is a sign of loss of estrogen. After 15 yrs of hot flashes, maybe it reached a very low plateau. I’m seeing a Naturopathic Doctor and started HRT for the debilitating anxiety.
Apparently hormonal changes can cause this. Although mainstream medicine puts timelines on female hormone changes, they have no evidence to show that our hormones don’t continue to change thru out our lives. Many elderly women experience sudden anxiety disorder. I pray to God that this is the source and can be mitigated.
