I am post menopause. I have a flushing and sweating problem often accompanied by chills before and after. I have tried many of the standard treatment and a complete endogrenology workup. Nothing there to indicate a reason. My mother suffered from the same thing most of her life. My issues with this started several years ago and has increased over the last few months . I have had two back surgeries and have fibromyalgia I take Lyrica and Prozac. Otherwise I am healthy.
