Cimicifuga is the remedy, but are you on any hormone treatment??
try cimicifuga c200 one dose first, then report back after some days.
Natr m could also be a choice, dep on symptomes, what you have given here, is to vague, only the hystrosectomia and removal of ovaries give one remedy cimicifuga, but the hiatus hernia can come from a other cause, as natr or kalium used during operation.
