I had a complete emergency hysterectomy over two years ago. I did not have any hot flashes and did not have to go on any hormones. For the last week I am having hot flashes and extreme chills. I lost my health coverage (after 30 years) due to inability to afford premiums and have gone about 30 days without my thyroid medication and I search for a provider that will see me without insurance. Could this be causing my symptons?
