I am having hot flashes. I had uterine cancer and had a hysterectomy that included ovaries and Fallopian tubes in 2007. I never had a problem with hot flashes then or ever. I developed Bell's Palsy 7 weeks ago and have changed my eating habits to include mainly protein and fruits and vegetables. I've lost 20 pounds in 7 weeks. I am very over weight still. I have been on Prednisone for the Bell's Palsy. I am also taking B Complex supplements. Is there another reason for hot flashes?
