I had a complete hysterectmy 15 years ago. I have been on HRT since. I have been getting a shot every 30 to 90 days for 15 years..mainly to keep the hot flashes somewhat at bay. Recently I have experienced terrible night sweats, worse than ever before, but they seem different than the hot flashes that drive me to get a hormone shot. Is this just symtomatic of regular menopause? After a shot, the hot flashes go away, and the night sweats used to, but now the night sweats stay with me...
