Women experience menopause in different ways. I had a hysterectomy at 41 but had one ovary left. When I finally went through menopause it was "nothing" that I could detect as different from everything I had lived through since the age of 17. In other words, I still had neurological symptoms but I did not have hot flashes at all. Nothing changed. The doctors misinterpreted my neuro symptoms as menopause, however, and put me on wild yam cream for hormones. I did this wild yam thing four different times, and each time reacted so badly (spasticity) within four days that I was off the yam. I later was shown to have Porphyria, which means those kind of hormones are not acceptable, so that later explained it. However, my point here is that, for me, menopause did not change me. I still had episodes of imbalance and other neuro problems, and spasticity, but no hot flashes, and I was no more temperamental than usual. But I suppose I've always been temperamental, so that does not mean much.

I would run not walk to the OR in your case. Best wishes for a great outcome.
