I also had a hysterectomy. I was perimenopausal but had minimal signs/symptoms. Within a few days of the hysterectomy (due to severe hemorrhaging secondary to a very large fibroid) and bilateral ovary removal (one enlarged cystic ovary and the other was "abnormal in appearance but functional"), I was started on an estrogen patch. All was well for about 10 days...then I developed a pulmonary embolism and that was the end of the estrogen replacement therapy. Instant menopause with serious hot flashes, night sweats/chills, and insomnia. Will be on coumadin for 3 more months for the blood thinning/clot treatment. Most meds interact with coumadin, so finding therapy for relief of symptoms is difficult. I will be on coumadin therapy for at least 3 more months, so need to be careful with medications and herbal/natural supplements. Any suggestions?
