Has this happened to anyone? Have had manageable hot flashes until now. One or two a night. Rarely in the day. Now, two years after official menopause, I am having hot flashes many times a day and night. Has anyone had a resurgence or increase over time after menopause? This is driving me nuts. I do not have hyperthyroidism. So definitely not that. If anything have had borderline hypothyroidism (no medication) which should make you cold. Instead breaking out in sweats randomly at any moment. Any experiences of increasing hot flashes years after menopause?
