Sadly pivoine, it is more likely the tamoxifen. Some side effects got better, some worse over the four years I took it (why did not make it to five)


A wild guess here, but I have seen threads before about irregular periods and other hormonal issues when starting LC. Read that it has to do with a rapid loss of visceral fat, which can release estrogen, fat being able to create and store estrogen. That hormonally active fat is a thoery why more obese women get breast cancer. When that fat is lost, the estrogen has to go somewhere, and for a period of time it recirculates, upsetting cycles..and maybe hot flashes?
It can rebalance your hormones too..or maybe throw them out of whack?

And for some women on LC, they get better:
