I had a full hysterectomy surgery 4 years ago this March: after 3 days of surgery, we, by the grace of God , discovered I had multiple pulmonary embolisms in both lungs. Wasn't long after two weeks of treatment and going home I discovered the "hell" of hot flashes. Sometime 20+ a day, still to this day. I go into panick a and can feel it started from my legs and slowly feel the temperature rising in my body like a thermometer. I turn blood red, sweat profusely, soaked hair, clothes and the worst feel like ant bites it can get so bad. The general ones last 2 to 5 minutes. I have some occasionally that last 10 to 12 minutes. Go away . Freeze to death (bone aching freezing) then within 10 minutes again. I have tried bio-identical made for me, I take an anti-depressant used for helping with hot flashes. Well, they don't work. I am so desperate for some relief. It's ruining my life.
