I had a hyster last year and have one remaining ovary. You are still
fairly new post op, complete recovery can take up to a year. I too have
occasional hot flashes and nite sweats. There is a great site that I
found called hyster sisters.. You can go there and see all sorts of
posts like hear, only all dealing with hysterectomy stuff... If you are
really concerned, check back with your doctor. There are tests that can
be done to see if your hormones are not up to par with your one ovary...
Good luck!
