Honestly this does sound like your MD is correct and I am going to recommend a product I feel will be of great help to you. It is all natural and can be found at all local drug stores and also Wal-Mart as well. I myself just turned 43 and am going through pre-menopause and this product has helped me wonderfully with the night sweats, hot flashes, as well as irritability. It is called Remifemin and you can find it near the pharmacy area of Wal-mart. And when your body goes throught those sweats it causes your body to be wet and that is when you tend to get the chills as that happpens to me and many women I know. I am going to include a link below about this product and I highly recommend you give it a try. And they have a day formula and a night formula now as well.
